Swift version: 5.4
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.
