(8.D.2.7) Sign
Overview
Computes the sign (-1, 0, or +1) of a floating-point value
Discussion
Computes the sign function of a floating-point number. The value returned is: -1.0 for x < 0, 0 for x = 0, and +1.0 for x > 0
For complex inputs, the function computes a complex output which equals X ./ abs(X). This is a unit vector that points in the same direction as X

M=sign_module(NAME)
Creates an Audio Weaver module that computes the function sign(x) of
a floating-point value. The value is:
sign(x) = 1.0 if x > 0
sign(x) = 0.0 if x == 0
sign(x) = -1.0 if x < 0
Arguments:
NAME - name of the module.
