Synopsis
Math.abs(x)
Arguments
- x
A positive or negative number.
Returns
The absolute value of x
(a positive number
of magnitude x
).
Description
The abs( )
method calculates the distance
between x
and
(also known as the absolute value of
x
). It leaves positive numbers unchanged
and converts negative numbers into positive numbers of the same
magnitude. It is useful for calculating the difference between two
numbers without regard to which is larger than the other. For
example, it is useful when calculating the distance between two
points because distances are always positive.
Example
Math.abs(-5); // Returns 5 // Calculate the difference between two numbers function diff (num1, num2) { return Math.abs(num1-num2); } diff(-5, 5); // Returns 10
