c# - Always return positive value

Question

I have a number it could be negative or positive but I simply want to return the positive value.

-4 -> 4
5 -> 5

I know I can do a simple if check, see if its zero then return it *-1 but I can't remember for the life of me what the actual Maths operator is!

Can anyone tell me what it is?

Answer 1

Use System.Math.Abs as documented here.
