Question: How do I use the function ldexp( ) in a program?
Answer: The math function ldexp( ) is used while solving the complex mathematical equations. This function takes two arguments, a double value and an int respectively. The order in which ldexp( ) function performs calculations is ( n * pow ( 2, exp ) ) where n is the double value and exp is the integer. The following program demonstrates the use of this function.#include <stdio.h> #include <math.h> void main( ) { double ans ; double n = 4 ; ans = ldexp ( n, 2 ) ; printf ( "nThe ldexp value is : %lfn", ans ) ; } Here, ldexp( ) function would get expanded as ( 4 * 2 * 2 ), and the output would be the ldexp value is : 16.000000 |
