I used the first quadrant 0 deg, 30 deg and 45 deg coordinates from the document.

Deg    0       30        45    Remark
X     7FFF    6EDD      5A83   These inputs are from the polar2rect results.
Y     01CC    3FFC      5A82

A    213E7     0         0     
R    8C54E   95906     7CF66

The results seems not right. What is the format of the input for X and Y?
Do I need to convert to unit circle? Is there any examples for the rect2polar, like the one for polar2rect in the document?

rect 2 polar

If I feed the core two sine waves, 90 degrees out of phase from a DDS (an I/Q signal) I should expect to see a constant magnitude (radius) and a linearly changing phase angle on the output.  This is not the generated output, however.
