# asfloat16
## Description
Reinterpret bits as a float16 (HLSL SM 6.2).
## Signature
half asfloat16(half value);
vector<half, N> asfloat16<int N>(vector<half, N> value);
matrix<half, R, C> asfloat16<int R, int C>(matrix<half, R, C> value);
half asfloat16(uint16_t value);
vector<half, N> asfloat16<int N>(vector<uint16_t, N> value);
matrix<half, R, C> asfloat16<int R, int C>(matrix<uint16_t, R, C> value);
half asfloat16(int16_t value);
vector<half, N> asfloat16<int N>(vector<int16_t, N> value);
matrix<half, R, C> asfloat16<int R, int C>(matrix<int16_t, R, C> value);
