Calculate the absolute value (modulus) of a real number.
| |x| | – |
Use this calculator for |x|: the distance from x to 0 on the number line. Negative inputs become positive; non-negative inputs stay as they are. |−4.2| is 4.2; |0| is 0.
This is the real absolute value, not the complex modulus of a + bi (see the complex-number page for |a| of the first number).
x: Any finite real number.
|x|: Absolute value, always ≥ 0.
