How to make a number positive using abs()
Swift version: 5.4
The abs() function returns the absolute value of a number, which is a way of describing how far away from zero it is without thinking about whether it’s positive or negative. It’s most commonly used if you have a number that you need to be positive, because whether you pass 30 or -30 to abs() you get back 30.
In code it’s just this:
let number = -15
let absolute = abs(number)That will set absolute to 15.
