Remainder is calculated in real domain.
a % b is identical to mod

You can use % to round a decimal number down to the nearest whole number. For example: If you wanted to use the command random to generate a whole number between 0 and 5, you could put this in a script:

_rand = random 6; _num = _rand - (_rand % 1);

In A1, the new commands round, floor or ceil would be the easier way to round.

: Be careful when dealing with negative numbers. The way a modulo operation treats negatives differs between languages. In SQF truncated division is used, hence:
-12 % -10 = -2 -12 % 10 = -2 12 % -10 = 2 12 % 10 = 2
