Re^3: Find if a number is a multiple of a number.

in thread Find if a number is a multiple of a number.

*Binary "%" computes the modulus of two numbers.Given integer operands
$a and $b: If $b is positive, then "$a % $b" is $a minus the largest
multiple of $b that is not greater than $a. If $b is negative then
"$a % $b" is $a minus the smallest multiple of $b that is not less than*

And... so what?

*$a (i.e. the result will be less than or equal to zero). Note that
when "use integer" is in scope "%" gives you direct access to the mod-
ulus operator as implemented by your C compiler. This operator is not
as well defined for negative operands, but it will execute faster.*

Is this the particular point on which you meant to draw the attention? If so, then it actually is a good point, however IMHO it belongs more to the realm of side notes...
