asfloat16

Description

Reinterpret bits as a float16 (HLSL SM 6.2).

Signature

half asfloat16(half value);

vector<half, N> asfloat16<N:int>(vector<half, N> value);

matrix<half, R, C> asfloat16<R:int, C:int>(matrix<half, R, C> value);

/// Requires Capability Set 1:
half asfloat16(uint16_t value);

/// Requires Capability Set 1:
vector<half, N> asfloat16<N:int>(vector<uint16_t, N> value);

matrix<half, R, C> asfloat16<R:int, C:int>(matrix<uint16_t, R, C> value);

/// Requires Capability Set 2:
half asfloat16(int16_t value);

/// Requires Capability Set 2:
vector<half, N> asfloat16<N:int>(vector<int16_t, N> value);

/// Requires Capability Set 3:
matrix<half, R, C> asfloat16<R:int, C:int>(matrix<int16_t, R, C> value);
