Functions
- __STATIC_INLINE int16_t riscv_typecast_s16_f16 (float16_t x)
Interpret a f16 as an s16 value.
- Description
It is a typecast. No conversion of the float to int is done. The memcpy will be optimized out by the compiler. memcpy is used to prevent type punning issues. With gcc, -fno-builtins MUST not be used or the memcpy will not be optimized out.
- Parameters
x – [in] input value.
- Returns
return value.
