Functions

__device__ ​ __half2 __hadd2 ( const __half2 a, const __half2 b )

Performs half2 vector addition in round-to-nearest-even mode.

Returns

Returns the half2 vector result of adding vectors a and b.

Description

Performs half2 vector add of inputs a and b, in round-to-nearest mode.

__device__ ​ __half2 __hadd2_sat ( const __half2 a, const __half2 b )

Performs half2 vector addition in round-to-nearest-even mode, with saturation to [0.0, 1.0].

Returns

Returns the half2 vector result of adding vectors a and b with saturation.

Description

Performs half2 vector add of inputs a and b, in round-to-nearest mode, and clamps the results to range [0.0, 1.0]. NaN results are flushed to +0.0.

Performs half2 vector fused multiply-add in round-to-nearest-even mode.

Returns

Returns the half2 vector result of the fused multiply-add operation on vectors a, b, and c.

Description

Performs half2 vector multiply on inputs a and b, then performs a half2 vector add of the result with c, rounding the result once in round-to-nearest-even mode.
