The result is the distance of the number from zero, so a negative input gives a positive result of the same size.

Formula

Absolute value of x is x if x is positive or zero, and −x if x is negative.

How it works

Enter any number. The calculator drops a minus sign if there is one. For example, the absolute value of −7 is 7.
