Computes the function y = ldexp(f,e) using the math library

Discussion

Computes the funtion function Y = ldexp(F, E) using the math library. The function computes a floating point number starting with a fractional value F and an exponent E as: Y = F * 2^E. This function is the inverse of frexp().

MATLAB Usage

File Name: frexpldexp_module.m

 M=frexpldexp_module(NAME)
 Creates an Audio Weaver module that computes the function frexp(xldexp(F, E)
 using the math library.  This function splitscomputes a floating point number
 numberstarting intowith a fractional fractionvalue F and an exponent E, suchas:
that the absolute   valueY 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* 2^E
 The function is the inverse of the function frexp().  Arguments:
    NAME - name of the module.
