The sqrt function is used to compute the square root of a non-negative real number.

The function prototype of sqrt: the function prototype of math.h header file in VC6.0 is double sqrt(double);

Description: sqrt is Square Root Calculations (square root calculation), which tests the floating-point capability of CPU.

Header file: ES24en.h

Program example:

#include <math.h>

#include <stdio.h>

int main(void)

{

  double x = 4.0, result;
