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.

__device__ ​ bool __hisnan ( const __half a )
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.

Performs half less-equal comparison.
Returns

Returns boolean result of less-equal comparison of a and b.

Description

Performs half less-equal comparison of inputs a and b. NaN inputs generate false results.

__device__ ​ bool __hleu ( const __half a, const __half b )
Performs half unordered less-equal comparison.
Returns

Returns boolean result of unordered less-equal comparison of a and b.

Description

Performs half less-equal comparison of inputs a and b. NaN inputs generate true results.
