I have additional question which is related to

https://e2e.ti.com/support/tools/ccs/f/81/p/961758/3555522#3555522

else if(10 <= X && X < 10000){

fxdLogX = -6 * (X - 5000) * (X - 5000) + 120040 * (X - 5000) - 1682360000;

Thanks to your support on above thread, customer was able to do additional verification to their code.

And, when X is 2000, final value of the expression is not overflow, but still there is the problem.

I can reproduce the same result. I agree overflow is not the problem. I filed the issue EXT_EP-10162 to have this investigated. You are welcome to follow it at that link.

Thanks and regards,

Analysis of this issue is not complete. But a good workaround to consider is to change the type of all the local variables to long long. Something like ...

int func_fail(int arg_X)
{
    long long X = arg_X;
    long long Y;
    long long fxdLogX;
...

Thanks and regards,
