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

[BarryMead]

Wouldn't something like this work equally well in DP mode, be fast, and use less memory since the
function cmplxFromPolar could be eliminated.

Code:


void op_p2r(enum nilop op) {
  decNumber x, y, t, range, angle;

  getXY(&range, &angle);
  decNumberCos(&t, &angle);
  dn_multiply(&x, &t, &range);
  decNumberSin(&t, &angle);
  dn_multiply(&y, &t, &range);
  setlastX();
  setXY(&x, &y);
#ifdef RP_PREFIX
  RectPolConv = 2;
#endif
}
