How to check class double number for non-zero decimals in an if statement?

I'm writing a GUI, and entries for specific edit text boxes are not supposed to contain decimals. I'm trying to use an if statement to tell whether or not a class double has non-zero numbers after the decimal point.

My goal is to give feedback with a 'msgbox' so that if a decimal is entered, the user is notified to enter an integer instead. Does anyone have any tips on how to properly define a condition to check for decimals in an if statement?

Thanks!

One approach would be to use the rem or mod functions:

x1 = 42.00;
y1 = rem(x1,1)

x2 = 42.42;
y2 = rem(x2,1)

y1 =
     0

y2 =
         0.42

Then test if the result is 0.
