Thread: Square Root??

If i have a number and i want to find the square root of it in a c program how could i go about this.

Thank,

Thanx guys,

here is the code of the program i made.

-------------------------------------------------------------------------------

/* MADE BY DANGEROUS DAVE 2001 with complments to matt*/
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
void main()

{
float a, b, c, s, u, v, w, x, y, z;
float ans1, ans2;

printf("Progran to find the roots of a quadratic equation useing the B rule\n");

printf("please enter A:\n");
scanf ("%f" , &a);
printf("Please enter B:\n");
scanf ("%f" , &b);
printf("Please enter C:\n");
scanf ("%f" , &c);

if (b<0)
{
b = b*-1;
}
x = b*b;
y = 4*a*c;
z = 2*a;
s = x-y;
s = sqrt (s);
ans1 = (b+s)/z;
ans2 = (b-s)/z;

printf("\nYour answers are (%f , %f)\n\n" , ans1 , ans2);

system("PAUSE");

}

any sugestions would be greatly recieved.

Thanx,
