The Math.abs() function returns the absolute value of a number. This means that it returns a number's positive value. You can think of it as the distance away from zero.

Create a function that recreates this functionality.

Examples

absolute(-1.217197940) ➞ 1.21719794

absolute(-12.1320) ➞ 12.132
 
absolute(-544.0) ➞ 544.0

absolute(4666) ➞ 4666.0

absolute(-3.14) ➞ 3.14

absolute(250) ➞ 250

Notes

• Tests will only include valid numbers.
• Don't use the Math.abs() function (it will defeat the purpose of the challenge).
