Revolt · Accepted Answer

The absolute value of a real number, is the distance from zero on the number line. The absolute value (modulus) of a complex number is the distance from origin in the complex plane, which for a bi is √(a² b²). Both are nonnegative, and for a real number interpreted as a 0i, the two definitions yield identical results.
