kfpsqrt
This command performs a square root operation on a real number and returns the result to the specified variable.
Usage
int kfpsqrt(double *x, double *z);
x
A variable that contains a floating point number
z
A variable where the result, the square root of x, is stored
Details
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).
Example
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.
