Troubleshooting Question

Float variable freezes after increasing

59 Views
Last Modified: 2021-01-08
I know, that it isn't a good way to increase a float variable inside a loop. But thats not the point.
And I know that most float numbers can't exactly convert to a binary number.
Can someone explain to me detailed the behaviour on case 1 and 2?

1) Why do the counters diverge?
2) Why does the second counter freeze after some time (I get after some time the same number even though I increase floatCtr by 0.1)?

int main()
{
    uint32_t uint32Ctr=0;
    float floatCtr=0;
    for(;uint32Ctr<=100000000;uint32Ctr++){
        floatCtr+=0.1;
        if(uint32Ctr%10000==0){
            printf("uint32 Counter = %d\t float Counter = %f\n", uint32Ctr, floatCtr);
        }
    }
    return 0;
}
