- * `format` string is composed of zero or more directives: ordinary characters (not %), which are copied unchanged - * to the output string and conversion specifications, each of which results in fetching zero or more subsequent - * arguments.

- * - * Each conversion specification is introduced by the character %, and ends with a conversion - * specifier. In between there may be (in this order) zero or more flags, an optional minimum field width - * and an optional precision.
- * The syntax is: ConversionSpecification = "%" { Flags } - * [ MinimumFieldWidth ] [ Precision ] ConversionSpecifier, where curly braces { } denote repetition - * and square brackets [ ] optionality.

- * - * By default, the arguments are used in the given order.
- * For argument numbering and swapping, `%m$` (where `m` is a number indicating the argument order) - * is used instead of `%` to specify explicitly which argument is taken. For instance `%1$s` fetches the 1st argument, - * `%2$s` the 2nd and so on, no matter what position the conversion specification has in `format`. - *

- * - * The flags
- * The character % is followed by zero or more of the following flags:
- * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - *
+ - * A sign (+ or -) should always be placed before a number produced by a - * signed conversion. By default a sign is used only for negative numbers. - *
0The value should be zero padded.
␣(a space) The value should be space padded.
'Indicates alternate padding character, specified by prefixing it with a single quote '.
-The converted value is to be left adjusted on the field boundary (the default is right justification).
- * - * The minimum field width
- * An optional decimal digit string (with nonzero first digit) specifying a minimum field width. If the converted - * value has fewer characters than the field width, it will be padded with spaces on the left (or right, if the - * left-adjustment flag has been given).

- * - * The precision
- * An optional precision, in the form of a period `.` followed by an optional decimal digit string.
- * This gives the number of digits to appear after the radix character for `e`, `E`, `f` and `F` conversions, the - * maximum number of significant digits for `g` and `G` conversions or the maximum number of characters to be printed - * from a string for `s` conversion.

- * - * The conversion specifier
- * A specifier that mentions what type the argument should be treated as: - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - *
`s`The string argument is treated as and presented as a string.
`d` `i`The integer argument is converted to signed decimal notation.
`b`The unsigned integer argument is converted to unsigned binary.
`c`The unsigned integer argument is converted to an ASCII character with that number.
`o`The unsigned integer argument is converted to unsigned octal.
`u`The unsigned integer argument is converted to unsigned decimal.
`x` `X`The unsigned integer argument is converted to unsigned hexadecimal. The letters `abcdef` are used for `x` - * conversions; the letters `ABCDEF` are used for `X` conversions.
`f` - * The float argument is rounded and converted to decimal notation in the style `[-]ddd.ddd`, where the number of - * digits after the decimal-point character is equal to the precision specification. If the precision is missing, - * it is taken as 6; if the precision is explicitly zero, no decimal-point character appears. - * If a decimal point appears, at least one digit appears before it. - *
`e` `E` - * The float argument is rounded and converted in the style `[-]d.ddde±dd`, where there is one digit - * before the decimal-point character and the number of digits after it is equal to the precision. If - * the precision is missing, it is taken as `6`; if the precision is zero, no decimal-point character - * appears. An `E` conversion uses the letter `E` (rather than `e`) to introduce the exponent. - *
`g` `G` - * The float argument is converted in style `f` or `e` (or `F` or `E` for `G` conversions). The precision specifies - * the number of significant digits. If the precision is missing, `6` digits are given; if the - * precision is zero, it is treated as `1`. Style `e` is used if the exponent from its conversion is less - * than `-6` or greater than or equal to the precision. Trailing zeros are removed from the fractional - * part of the result; a decimal point appears only if it is followed by at least one digit. - *
`%`A literal `%` is written. No argument is converted. The complete conversion specification is `%%`.

\n * `format` string is composed of zero or more directives: ordinary characters (not %), which are copied unchanged\n * to the output string and conversion specifications, each of which results in fetching zero or more subsequent\n * arguments.

\n *\n * Each conversion specification is introduced by the character %, and ends with a conversion\n * specifier. In between there may be (in this order) zero or more flags, an optional minimum field width\n * and an optional precision.
\n * The syntax is: ConversionSpecification = \"%\" { Flags }\n * [ MinimumFieldWidth ] [ Precision ] ConversionSpecifier, where curly braces { } denote repetition\n * and square brackets [ ] optionality.

\n *\n * By default, the arguments are used in the given order.
\n * For argument numbering and swapping, `%m$` (where `m` is a number indicating the argument order)\n * is used instead of `%` to specify explicitly which argument is taken. For instance `%1$s` fetches the 1st argument,\n * `%2$s` the 2nd and so on, no matter what position the conversion specification has in `format`.\n *

\n *\n * The flags
\n * The character % is followed by zero or more of the following flags:
\n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n *
+\n * A sign (+ or -) should always be placed before a number produced by a\n * signed conversion. By default a sign is used only for negative numbers.\n *
0The value should be zero padded.
␣(a space) The value should be space padded.
'Indicates alternate padding character, specified by prefixing it with a single quote '.
-The converted value is to be left adjusted on the field boundary (the default is right justification).
\n *\n * The minimum field width
\n * An optional decimal digit string (with nonzero first digit) specifying a minimum field width. If the converted\n * value has fewer characters than the field width, it will be padded with spaces on the left (or right, if the\n * left-adjustment flag has been given).

\n *\n * The precision
\n * An optional precision, in the form of a period `.` followed by an optional decimal digit string.
\n * This gives the number of digits to appear after the radix character for `e`, `E`, `f` and `F` conversions, the\n * maximum number of significant digits for `g` and `G` conversions or the maximum number of characters to be printed\n * from a string for `s` conversion.

\n *\n * The conversion specifier
\n * A specifier that mentions what type the argument should be treated as:\n *\n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n * \n *\n *
`s`The string argument is treated as and presented as a string.
`d` `i`The integer argument is converted to signed decimal notation.
`b`The unsigned integer argument is converted to unsigned binary.
`c`The unsigned integer argument is converted to an ASCII character with that number.
`o`The unsigned integer argument is converted to unsigned octal.
`u`The unsigned integer argument is converted to unsigned decimal.
`x` `X`The unsigned integer argument is converted to unsigned hexadecimal. The letters `abcdef` are used for `x`\n * conversions; the letters `ABCDEF` are used for `X` conversions.
`f`\n * The float argument is rounded and converted to decimal notation in the style `[-]ddd.ddd`, where the number of\n * digits after the decimal-point character is equal to the precision specification. If the precision is missing,\n * it is taken as 6; if the precision is explicitly zero, no decimal-point character appears.\n * If a decimal point appears, at least one digit appears before it.\n *
`e` `E`\n * The float argument is rounded and converted in the style `[-]d.ddde±dd`, where there is one digit\n * before the decimal-point character and the number of digits after it is equal to the precision. If\n * the precision is missing, it is taken as `6`; if the precision is zero, no decimal-point character\n * appears. An `E` conversion uses the letter `E` (rather than `e`) to introduce the exponent.\n *
`g` `G`\n * The float argument is converted in style `f` or `e` (or `F` or `E` for `G` conversions). The precision specifies\n * the number of significant digits. If the precision is missing, `6` digits are given; if the\n * precision is zero, it is treated as `1`. Style `e` is used if the exponent from its conversion is less\n * than `-6` or greater than or equal to the precision. Trailing zeros are removed from the fractional\n * part of the result; a decimal point appears only if it is followed by at least one digit.\n *

- * `format` string is composed of zero or more directives: ordinary characters (not %), which are copied unchanged - * to the output string and conversion specifications, each of which results in fetching zero or more subsequent - * arguments.

- * - * Each conversion specification is introduced by the character %, and ends with a conversion - * specifier. In between there may be (in this order) zero or more flags, an optional minimum field width - * and an optional precision.
- * The syntax is: ConversionSpecification = "%" { Flags } - * [ MinimumFieldWidth ] [ Precision ] ConversionSpecifier, where curly braces { } denote repetition - * and square brackets [ ] optionality.

- * - * By default, the arguments are used in the given order.
- * For argument numbering and swapping, `%m$` (where `m` is a number indicating the argument order) - * is used instead of `%` to specify explicitly which argument is taken. For instance `%1$s` fetches the 1st argument, - * `%2$s` the 2nd and so on, no matter what position the conversion specification has in `format`. - *

- * - * The flags
- * The character % is followed by zero or more of the following flags:
- * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - *
+ - * A sign (+ or -) should always be placed before a number produced by a - * signed conversion. By default a sign is used only for negative numbers. - *
0The value should be zero padded.
␣(a space) The value should be space padded.
'Indicates alternate padding character, specified by prefixing it with a single quote '.
-The converted value is to be left adjusted on the field boundary (the default is right justification).
- * - * The minimum field width
- * An optional decimal digit string (with nonzero first digit) specifying a minimum field width. If the converted - * value has fewer characters than the field width, it will be padded with spaces on the left (or right, if the - * left-adjustment flag has been given).

- * - * The precision
- * An optional precision, in the form of a period `.` followed by an optional decimal digit string.
- * This gives the number of digits to appear after the radix character for `e`, `E`, `f` and `F` conversions, the - * maximum number of significant digits for `g` and `G` conversions or the maximum number of characters to be printed - * from a string for `s` conversion.

- * - * The conversion specifier
- * A specifier that mentions what type the argument should be treated as: - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - *
`s`The string argument is treated as and presented as a string.
`d` `i`The integer argument is converted to signed decimal notation.
`b`The unsigned integer argument is converted to unsigned binary.
`c`The unsigned integer argument is converted to an ASCII character with that number.
`o`The unsigned integer argument is converted to unsigned octal.
`u`The unsigned integer argument is converted to unsigned decimal.
`x` `X`The unsigned integer argument is converted to unsigned hexadecimal. The letters `abcdef` are used for `x` - * conversions; the letters `ABCDEF` are used for `X` conversions.
`f` - * The float argument is rounded and converted to decimal notation in the style `[-]ddd.ddd`, where the number of - * digits after the decimal-point character is equal to the precision specification. If the precision is missing, - * it is taken as 6; if the precision is explicitly zero, no decimal-point character appears. - * If a decimal point appears, at least one digit appears before it. - *
`e` `E` - * The float argument is rounded and converted in the style `[-]d.ddde±dd`, where there is one digit - * before the decimal-point character and the number of digits after it is equal to the precision. If - * the precision is missing, it is taken as `6`; if the precision is zero, no decimal-point character - * appears. An `E` conversion uses the letter `E` (rather than `e`) to introduce the exponent. - *
`g` `G` - * The float argument is converted in style `f` or `e` (or `F` or `E` for `G` conversions). The precision specifies - * the number of significant digits. If the precision is missing, `6` digits are given; if the - * precision is zero, it is treated as `1`. Style `e` is used if the exponent from its conversion is less - * than `-6` or greater than or equal to the precision. Trailing zeros are removed from the fractional - * part of the result; a decimal point appears only if it is followed by at least one digit. - *
`%`A literal `%` is written. No argument is converted. The complete conversion specification is `%%`.
