Hello Everybody.
I used atan2() functoin
ETheta = _IQ15atan2( _IQ15(0.5), _IQ15(0.866) ) ;
But result is '0' ( It should be '17157')
I don't know why ?
And I have tried _IQmpy, it's right.
Thanks a lot.
Environment :
IQmath V16.0, I have include IQmathLib.h , 2806x_IQmath_BootROMSymbols_fpu32.lib , IQmath_fpu32.lib
And the compiler is warning like this
