(8.D.2.5) 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.

MATLAB Usage

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.
