| // Fast half-precision to single-precision floating point conversion | |
| // - Supports signed zero and denormals-as-zero (DAZ) | |
| // - Does not support infinities or NaN | |
| // - Few, partially pipelinable, non-branching instructions, | |
| // - Core opreations ~6 clock cycles on modern x86-64 | |
