Frexp

Overview

Computes the function [f,e] = frexp(x) using the math library

Discussion

Computes the function [f, e]=frexp(x) using the math library. This function splits a floating point number into a fraction F and an exponent E, such that the absolute value of F is in the range [0.5 1.0) and such that 2^E * F equals the input value. The output pin 'f' is a floating-point value and the output pin 'e' is an integer.

File Name: frexp_module.m

 M=frexp_module(NAME)
 Creates an Audio Weaver module that computes the function frexp(x)
 using the math library.  This function splits a floating point 
 number into a fraction F and an exponent E, such that the absolute 
 value of F is in the range [0.5 1.0) and such that 2^E * F equals
 the input value.  The output F is a floating-point value; the output
 E is an integer.  Arguments:
    NAME - name of the module.
