# Function MOD

Hi experts,

I have 2 values: A and B. I'm using the function MOD.

if A > B then
result := A mod B
if A < B then
result := B mod A

I'm just wondering whether there is a shorter way to write this using the function MOD. I mean whether there is a way that the program will detect which value is bigger and do the function for you. Thank you.

you can use

uses Math

result := Max(A,B) mod Min(A,B);

You have to watch out for the special cases which should be tested for on input:-

A=B (not explicitly catered for in the asker's example)

A=0; B>A
B=0; A>B

in any solution that is chosen.
Commented:
uses Math
A := IfThen(A <> 0, A, B)
B := IfThen(B <> 0, B, 1)
result := Max(A,B) mod Min(A,B);

Hope this helps.
