WP-34S Polar to Rectangular (no quadrant checking)

[BarryMead]

The "Rectangular to Polar" works just fine. It is only the "Polar to Rectangular" that has problems with three of the four quadrants! At angles 90, 180 and 270 the value that should return as zero comes back as a tiny value like 3.799 E -39 instead of zero. Since all other HP calculators that I can run tests on do the Polar to Rectangular conversion correctly (only the WP-34S has these inaccuracies), and since these four angles are more common than others, I would think that people would want this to be fixed. The new Polar to Rectangular function would be: NewX = X COS(Y) and NewY = X SIN(Y), using the existing SIN and COS functions that already handle these special quadrant angles properly.
