Functions
- __device__ bool __heq ( const __half a, const __half b )
-
Performs half if-equal comparison.
Returns
Returns boolean result of if-equal comparison of a and b.
Description
Performs half if-equal comparison of inputs a and b. NaN inputs generate false results.

-
Performs half unordered if-equal comparison.
Returns
Returns boolean result of unordered if-equal comparison of a and b.
Description
Performs half if-equal comparison of inputs a and b. NaN inputs generate true results.
- __device__ bool __hge ( const __half a, const __half b )
-
Performs half greater-equal comparison.
Returns
Returns boolean result of greater-equal comparison of a and b.
Description
Performs half greater-equal comparison of inputs a and b. NaN inputs generate false results.
- __device__ bool __hgeu ( const __half a, const __half b )
-
Performs half unordered greater-equal comparison.
Returns
Returns boolean result of unordered greater-equal comparison of a and b.
Description
Performs half greater-equal comparison of inputs a and b. NaN inputs generate true results.
- __device__ bool __hgt ( const __half a, const __half b )
-
Performs half greater-than comparison.
Returns
Returns boolean result of greater-than comparison of a and b.
Description
Performs half greater-than comparison of inputs a and b. NaN inputs generate false results.
- __device__ bool __hgtu ( const __half a, const __half b )
-
Performs half unordered greater-than comparison.
Returns
Returns boolean result of unordered greater-than comparison of a and b.
Description
Performs half greater-than comparison of inputs a and b. NaN inputs generate true results.
- __device__ int __hisinf ( const __half a )
-
Checks if the input half number is infinite.
Returns
Returns -1 iff a is equal to negative infinity, 1 iff a is equal to positive infinity and 0 otherwise.
Description
Checks if the input half number a is infinite.

-
Determine whether half argument is a NaN.
Returns
Returns boolean true iff argument is a NaN, boolean false otherwise.
Description
Determine whether half value a is a NaN.
