Math.abs()
The Math.abs() function returns the absolute value of a number.
Syntax
Math.abs(x)
Parameters
x- : A number.
Return value
The absolute value of x. If x is negative (including -0), returns -x. Otherwise, returns x. The result is therefore always a positive number or 0.
Description
Because abs() is a static method of Math, you always use it as Math.abs(), rather than as a method of a Math object you created (Math is not a constructor).
