Summary

Declaration

Definition

from hal_utils.h:182

int hal_utils_float_to_fixed_point_32b(float flt, const hal_utils_fixed_point_t *fp_cfg, uint32_t *fp_out);

Implemented in hal_utils.c:152

Arguments

Argument

Description

flt

IEEE 754 float type data

fp_cfg

Fixed-point data configuration

fp_out

The output fixed-point data

Return value

0: Success -1: Fixed point data overflow, `fp_out` will still be assigned -2: Float is NaN -3: Invalid configuration

Notes

The supported data format: - [input] float (IEEE 754): sign(1bit) + exponent(8bit) + mantissa(23bit) (32 bit in total) - [output] fixed-point: sign(1bit) + integer(int_bit) + fraction(frac_bit) (less or equal to 32 bit)
