Check if a square root is a whole number

[BALA]

How can I check if the number produced after finding the square root of a number is a whole number?

If IsInt()?

$a = '3'
$b = '3.2'

If IsInt(Number($a)) Then MsgBox(0, 1, $a)
If IsInt(Number($B)) Then MsgBox(0, 2, $B)

Back to the help file for you...

IsInt() works in AutoIt becasue it does not use typed variables, but rather variants that use heuristics (hints from the data itself) to determine data-type.

In other languages (and if AutoIt too if you want to) you would use the Mod function e.g.

If Mod($number, 1) = 0 Then 
    ; it's a whole number
Else
    ; not a whole number
EndIf

I didn't think of searching for "integer" since integers contain the set of negative numbers, but i guess in AutoIt they're interchangeable with Whole numbers. Well thanks then.

EDIT: strike that about them being interchangeable, it returns 1 for negatives.

Sorry, I'm not familiar with modulus operation, what exactly is Mod() doing?

I do that every time someone asks this question, and you are always right there to show the "proper" way. The funny thing is, in my own code (a tad more thought put into it obviously, I use MOD myself).

Ha! Not really trying to one-up you -- I had just started writing a reply when I noticed you had already chimed in.

@bala - many sources... see Wikipedia - Modulo Operation
