Supplement the field calculator help for the % operator and the Floor function

[pigreco]

Feature description

Operator %:

In case the Dividend is smaller than the Divisor, the remainder is always equal to the Dividend: example 10 % 20 --> 10;

it would be nice and helpful to add it in the guide and also add an example.

Floor function

The Floor Function corresponds (?) to the // operator: example floor(2/26) = 2//26

also in this case it would be nice and useful to read it in the guide

Additional context

I also have wanted the documentation to mention modulo because that is what I search for.
Although according to this stack exchange it seems it is not a true modulo operator because it takes the sign of the dividend not the divisor.
So, in addition to your proposal I would like to add text saying Similar to modulo so I can search for it. And examples -9 % 2 --> -1 and 9 % -2 --> 1

Is the Floor function suggestion a duplicate of #52094?
