Absolute Value Calculator
Find the absolute value (distance from zero) of a number — or a whole list of numbers at once. Enter one or more real numbers, separated by commas, spaces, or new lines, and see each one's sign and absolute value in a table.

Guides
The Absolute Value Calculator finds |x| — the distance of a number from zero on the number line — for one number or a whole list at once. Enter one or more real numbers, separated by commas, spaces, or new lines, and it instantly returns each number's sign and absolute value in a table.
It's built for students checking homework, anyone cleaning up a dataset of signed values (deltas, temperature changes, errors), or checking a batch of numbers in one pass instead of one at a time.
How to use it
- Enter one or more numbers (up to 500 at a time) in the Numbers field, separated by commas, spaces, or new lines. Decimals and negative numbers are both supported.
- Read the Result table: each number, whether it's negative, positive, or zero, and its absolute value.
Results update automatically as you type. For example, entering -12.5, 7, -3.2 returns 12.5, 7, and 3.2.
What is absolute value?
The absolute value of a number is its distance from zero, always expressed as a non-negative number. For a positive number or zero, the absolute value is the number itself; for a negative number, it's the number with its sign flipped. Written mathematically, |x| = x if x ≥ 0, and |x| = -x if x < 0.
Why does absolute value matter?
Absolute value shows up anywhere the size of a difference matters more than its direction — measuring error margins, temperature swings, distances on a number line, or the magnitude of a financial gain or loss regardless of whether it was positive or negative.
