(8.D.2.1) Ldexp

Overview

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

Discussion

Computes the 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().
