'''Absolute Value'''
The absolute value of a real number x (symbolized |x|) is the unsigned portion of x<ref>http://mathworld.wolfram.com/AbsoluteValue.html</ref> . The absolute value of x is always greater than or equal to 0.
The absolute value of a complex number z (also symbolized as |z|) is the complex modulus of z. If <math>z = \x+i*y</math> where x and y are real and <math>x : f(x) = 0\,</math> then the complex modulas of z is <math>\sqrt{2}</math>
