Rounding number without "Round half to even"

[tomaskodaj]

Is it possible to introduce standard mathematical round function, or introduce switch to change behavior of $round()

Expected output:

$roundX(11.5) => 12
$roundX(12.5) => 13

We are using jsonata for financial calculations where current behavior is not desired and we have to do obscure transformations because of current behavior :(

Thanks

Docs:

This function uses the Round half to even strategy to decide which way to round numbers that fall exactly between two candidates at the specified precision. This strategy is commonly used in financial calculations and is the default rounding mode in IEEE 754.

$round(11.5) => 12
$round(12.5) => 12
