8-118
This example adds the data in res1 to the data in res2. The result is stored in the resia
variable.
double res1, res2, resia;
.
.
measv(SMU1, &res1);/* Measure SMU1 voltage; store */
/* in res1. */
measi(SMU2, &res2);/* Measure SMU2 current; store */
/* in res2. */
kfpadd(&res1, &res2, &resia);/* Adds res1 and res2; return */
/* result to resia. */
Divides two real numbers and stores the result in a specified variable.
int kfpdiv(double *x, double *y, double *z);
The dividend.
x
The divisor.
y
A variable where the result of x/y will be stored.
z
The value referenced by x will be divided by the value referenced by y, and the result
will be stored in the location pointed to by z. If an overflow occurs, the result will be
±Inf. If an underflow occurs, the result will be zero (0).
This example divides the data in res1 by the data in res2. The result is stored in the
resia variable.
double res1, res2, resia;
.
.
measv(SMU1, &res1);/* Measure SMU1 voltage; store */
/* in res1. */
measi(SMU2, &res2);/* Measure SMU2 current; store */
/* in res2. */
kfpdiv(&res1, &res2, &resia);/* Divide res1 by res2; return */
/* result to resia. */
