TMS320F280049C: Arguments order of atan2 function.

Part Number: TMS320F280049C

Hi all,

I am looking for the TI description file for math floating library,

How to call any function from math library with the correct arguments order,

I am using TMS320F280049C floating point device to calculate Arctan(x,y). The TI function I am using is float atan2(float x, float y), the issue is, I am not sure for what x and y correspond to?

Best regards,

I'd expect x is the real part (x-axis), and y is the imaginary part (y-axis) of the complex number. A quick test with the function should confirm this.

Regards,
David
