This calculator returns the absolute value of a number — its distance from zero on the number line, ignoring sign. It also shows the difference between the entered number and its absolute value for context.
Frequently asked questions
What is absolute value?
It's the non-negative value of a number without regard to its sign, so both 5 and -5 have an absolute value of 5.
Does absolute value change positive numbers?
No, positive numbers and zero are unchanged since they are already non-negative.
Where is absolute value used?
It's commonly used to measure distance, error margins or differences where direction doesn't matter.
