Write a recursive function to find square root of a number

Write a recursive function to find square root of a number.

#include "math.h"

#include "float.h"

float MySqrt(float num, float prev)

{

    float next = (prev+num/prev)/2;

    if (fabs(next-prev)<FLT_EPSILON*next)

        return next;

    return MySqrt(num, next);

}

To call it, pass 1.0 as your initial guess for the prev parameter.
