Absolute Value
The absolute value of a real number x (symbolized |x|) is the unsigned portion of x[1] . 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 z = x+i*y where x and y are real and i= then the complex modulas of z is
