Global Functions
dnnl_fpmath_mode_t dnnl::convert_to_c(fpmath_mode mode)Converts an fpmath mode enum value from C++ API to C API type.
Parameters:
| mode | C++ API fpmath mode enum value. | 
Returns:
Corresponding C API fpmath mode enum value.
dnnl_status_t DNNL_API dnnl_get_default_fpmath_mode(dnnl_fpmath_mode_t* mode)Returns the floating-point math mode that will be used by default for all subsequently created primitives.
Parameters:
| mode | Output FP math mode. | 
Returns:
dnnl_success on success and a status describing the error otherwise.
dnnl_status_t DNNL_API dnnl_set_default_fpmath_mode(dnnl_fpmath_mode_t mode)Sets the floating-point math mode that will be used by default for all subsequently created primitives.
Parameters:
| mode | FP math mode. The possible values are: dnnl_fpmath_mode_strict, dnnl_fpmath_mode_bf16, dnnl_fpmath_mode_f16, dnnl_fpmath_mode_tf32, dnnl_fpmath_mode_any. | 
Returns:
dnnl_success on success and a status describing the error otherwise.
