IQMath Pow problem

Ronen Yuval Hoch

I'm running the following code :

int i;
float a = -2.123;
int x = 3;
float resTemp,res;

_iq a1 = _FtoIQ(a);
_iq x1 = _IQ(x);
_iq b1 = _IQpow(a1,x1);
resTemp = _IQtoF(b1);

I'm getting resTemp = 9.568631 instead of having resTemp = -9.568631.

Does anyone have any idea why I'm not getting the minus sign? I've to run this example with integers only and I see the same phenomena.

Thank you,

Ronen

I think that this message will get answered more rapidly if it is moved to the Code Gen forum.

The IQmath library is not part of the compiler package. But before I refer you on, please answer these questions.

Which target? What version of the library? What version of the compiler? What compiler build options are you using?

Thanks and regards,

George,

I see the same issue, the target is c64x+sim and I'm using CCS3.3, CGT v6.1.9, BIOS 5.33.06, IQmath v213 and no special build options (debug),

Many Thanks,

I'll move this thread to a C6000 processor specific forum.

Thanks and regards,
