absolute value (complex number)


Also called the modulus of a complex number. The modulus of a complex number z = x + yi, denoted as z, is defined as (x^{2}+y^{2})^{1/2}. It is the distance between the origin and the point representing the complex number.
For example, the absolute value of 3 + 4i is (3^{2} + 4^{2})^{1/2} = 5.
