I'm making a program to find the perimeter of any shape, and it's separated into two sections: polygons, and non-polygons. My polygon section works interestingly, in which it asks the user for the number of sides and then let's you input numbers until the number of entries reaches the number of sides. I have a feature implemented that makes sure one enters a number 3 or greater (because polygons have to have 3 or more sides) but is there a way to make sure one enters a whole number (because you can't have a polygon with 2.8, 4.87, etc. sides)?
Sure, just check if the number rounded down is the same as the number, i.e.
Code:
If A=int(A)
Another trick is to check if the decimal part is equal to 0, like this:
Code:
If not(fPart(A
