Where is the MOD (modulus operator)?

Where is the MOD (modulus operator)?

Why does synergy-DBL not have a modulus operator?

Which is the easiest way of finding out if a number is divisble by another number?


RE: Where is the MOD (modulus operator)?

I create the following function, stuck it in a library, and link my apps with it.

;   Return the modulus of two numbers
;   By Paul Fenton
;   Usage:  modulus = a_num1 / a_num2
;   example:  modulus = %mod(9,2)
;   answer:   1
.function mod, ^val
    a_num1        ,n        
    a_num2        ,n        
    freturn (a_num1 - ((a_num1 / a_num2) * a_num2))

This code needs error checking. It will abort with a divide by zero error if a_num2 is zero.

RE: Where is the MOD (modulus operator)?

Serves you right if you ask for %mod(num, 0).

All seriousness aside <g>, you can use onerror ($ERR_CATCH) and trap a divide by zero error outside the function for this case.  Otherwise, the function has no meaningful return value for a modulo 0.
