Parameters
| Input | ||
| Name | Type | Description |
|---|---|---|
| specialViReal64Type | ViReal64 | Specifies the type of the special ViReal64 value you want to obtain: Valid Values: (1) IVI_VAL_TYPE_NAN—Not a Number (NaN) (2) IVI_VAL_TYPE_PINF—positive infinity (3) IVI_VAL_TYPE_NINF—negative infinity All other values are coerced to IVI_VAL_TYPE_NAN. |
Return Value
A pointer to a special ViReal64 value based on the value of the specialViReal64Type parameter.
