[[Complex number]]s also have an absolute value.  If <math>z = x+iy</math> is a complex number with real part <math>x</math> and imaginary part <math>y</math>, then <math>|z| = \sqrt{x^2 + y^2}</math>.  If we represent <math>z</math> as a point in the complex plane with coordinates <math>(x,y)</math>, then <math>|z|</math> is the distance from this point to the origin.  The absolute value of complex numbers also has the multiplicative property and satisfies the triangle inequality.
