Use arcade to check if a number is even or odd

[CameronLacelle]

Is there a way in arcade to take a value and determine if it is an odd or even number? I have an if statement within a for loop and want the function to perform differently when my var i is even versus when it is odd. This is for the purpose of colouring table rows differently as I am building an HTML string from my arcade script.

Hey @CameronLacelle 

This script here should help, this uses the % operator to check the remainder of the number divided by 2, if zero, then it is even, else it is odd.

var number = 7
var isEven = (number % 2 == 0)
if (isEven) {
    return "Even"
} else {
    return "Odd"
}

You'd replace the return with your function and you'll be set!

Divide by 2 and check for a remainder.  If the remainder is 0 its and even number.  Use the Modulus (%) operator in Arcade to get the remainder.
