C/Math/Square Root
Calculate square root: how to use sqrt
<source lang="cpp">
- include <stdio.h>
- include <math.h>
int main () {
double param, result;
param = 1024.0;
result = sqrt (param);
printf ("sqrt(%lf) = %lf\n", param, result );
return 0;
}
</source>
Get the square root
<source lang="cpp">

- include <math.h> /* needed by sqrt() */
int main(void) {
double answer;
answer = sqrt(20.0);
printf("%f", answer);
return 0;
