kfpsqrt

This command performs a square root operation on a real number and returns the result to the specified variable.

int kfpsqrt(double *x, double *z);

The square root of the value referenced by x is stored in the location pointed to by z.

If x points to a negative number, a square root of negative number error is generated, and the result

is NaN (not a number).

double res1, sqres2;

measv(SMU1, &res1);/* Measure SMU1; store result */

./* in res1. */

kfpsqrt(&res1, &sqres2);/* Find square root of res1; */

/* return result to sqres2. */

This example converts a real number (res1) into its square root. The result is stored in sqres2.
