4q Fp Pf Data Type Direct
int main() float original = 3.14159f; q4_12_t fixed = float_to_q4_12(original); float restored = q4_12_to_float(fixed);
Check your compiler’s fixed-point.h or stm32_dsp.h header file. You’ll likely find #define Q4_12 or similar. Have you encountered a different interpretation of "4q fp pf"? Let me know in the comments — datasheets can be wild. 4q fp pf data type
// Packing example uint32_t packed = pack_q4_12_pair(fixed, fixed); printf("Packed PF (32-bit): 0x%08X\n", packed); int main() float original = 3
return 0;
printf("Original: %f\n", original); printf("Q4.12 fixed-point integer: %d\n", fixed); printf("Restored: %f\n", restored); int main() float original = 3.14159f
