Modulo Operation For Macex


Recommended Posts

I needed a quick-and-dirty Modulo calculation so I just wrote this from scratch. Here's my macro which works as a basic calculator.

 

Modulo operation as defined in Wikipedia

In computing, the modulo operation finds the remainder of division of 
one number by another.

Given two numbers, a and n, a modulo n (abbreviated as a mod n) is 
the remainder, on division of a by n.

To calculate:

a mod n

a - n (floor( a / n ))

 

This macro has only been lightly tested, but it appears to work for me. The macro returns the same results as the Modulo function in Win XP's Calculator (Scientific view).

 

Of course, you can also get a Modulo (Mod) function from PG Macros:

But I didn't want to install PG Macros just for one function.

Perfect! The one in our PGM Functions Library uses Decimals %Dxx% and extra step to extract just the whole number. The { Math - Mod } function was created before Macro Express had the ability to mix Integers and Decimals in a single calculation.

 

Speaking of fun things, the { Math - Square Root } function was done with native Macro Express code using a "divide and average" method ... it must have been a day when I had a lot of time on my hands ;)
