Dear

I'm using IQ math lib global Q value is set to 19. Could something explain me. Why

_iq a,

a=_IQdiv(_IQ(2),_IQ(2))

I'm getting value of a equal to zero?

Hi Sargis,

Seems odd. Do check the IQMath user guide from here:
C:\ti\controlSUITE\libs\math\IQmath\v160\doc

It has a sample example for _IQdiv operation. Did you try with float numbers instead of integer 2?

Regards,
Gautam

No, I used TI c2800 simulator, but in target it was working ok.

Thanks

That makes sense! C2800 Simulator might not be recognizing IQMath then. Have not worked with Simulator but that should be the case!
