How to Use the Absolute Value Calculator
The Absolute Value Calculator finds the absolute value and sign of any integer, decimal, or fraction. Absolute value represents the distance of a number from zero on the number line β it is always zero or positive regardless of the original sign.
Select Integer/Decimal to enter a single number, or select Fraction to enter a numerator and denominator separately. The result shows both the absolute value and whether the number is positive, negative, or zero.
Definition and Formula
|x| = x when x β₯ 0; |x| = βx when x < 0. Examples: |β7.5| = 7.5, |3/4| = 3/4 = 0.75, |0| = 0. The absolute value of a β b gives the distance between a and b on the number line.
Frequently Asked Questions
Absolute value measures distance, which cannot be negative. The sign of the original number is removed, leaving only its magnitude.
Yes. β3/4 = β0.75. You can enter either form and get the same absolute value of 0.75.
|β0| = 0. Zero has no sign and its absolute value is 0.
