absolute value(redirected from Absolute Values)
Also found in: Dictionary, Thesaurus, Financial.
absolute value,magnitude of a number or other mathematical expression disregarding its sign; thus, the absolute value is positive, whether the original expression is positive or negative. In symbols, if |a| denotes the absolute value of a number a, then |a| = a for a > 0 and |a| = −a for a < 0. For example, |7|= 7 since 7 > 0 and |−7| = −(−7), or |−7| = 7, since −7 < 0.

For a complex number, the square root of the sum of the squares of its real and imaginary parts. Also known as modulus.
