How to use the Absolute Value Calculator

Absolute value is a number’s distance from zero on the number line, so it is never negative. Enter any finite number to return its absolute value.

Formula

|x| = x when x ≥ 0; |x| = −x when x < 0

Worked example

The absolute value of −12.5 is 12.5. The absolute value of 12.5 is also 12.5.

What to keep in mind

  • Absolute value ignores whether the original number is to the left or right of zero.
  • The absolute value of zero is zero.
  • Decimal values are supported.
