I want to convert a negative int/ double value into positive of the same

Question

I want to convert a negative int/ double value into positive of the same, and use it for further calculations..i tried using %2 but the value turns out to be -0.0. It would be a great help if someone could help me out with this.

Answer 1

In Dart you can do like this

value.abs()

In Kotlin you can do like this

value.absoluteValue

In JavaScript you can do like this

Math.abs(value)

Answer 2

If you only want to change negative numbers you could do:

if(num < 0)
    num *= -1;
