Using complex numbers in EQW on the 50g? Message #1 Posted by Ken Ratkevich on 29 Nov 2006, 11:44 a.m. I would like to use complex numbers in EQW in polar form using the representation (r,<theta) but it doesn't seem to work at all. The representation r*e^(i*theta) is taken by EQW and returned to the stack when ENTERed, but ->NUM returns the wrong ordered pair of numbers. The representation r*cos(theta)+i*r*sin(theta) is taken by EQW, returned to the stack when ENTERed AND ->NUM returns the correct ordered pair of numbers. Are my observations correct? I would really rather use the (r,<theta) representation. Ken

I guess this has been discussed before. Message #2 Posted by Ken Ratkevich on 30 Nov 2006, 7:14 a.m., in response to message #1 by Ken Ratkevich It appears EQW will handle any (I think) ALPHA /-> keypad combination except ALPHA /-> 6. Maybe I'm just asking for too much from the 50g. Ken
