Double (or float) division does not work

[JR2963]

Hi,

on STM32H7 I want to divide 25600/1000 - I get always result = 25. Why? What I do wrong?

double 		freq;
int                    odr=25600;
 
freq = (double) (odr)/1000;

Thank you

One last thing, refrain from using float and double under interrupt.

Though it's not an absolute rule. One just have to understand what he is doing and what are the consequences:
