Soft menus

[Djames]

I don't think this is made for professional engineers/surveyors . I am pulling my hair out to do basic problems.. Converting angles . Seems it wants degree symbols etc to enter for conversion, all other hp you enter the deg.minsec , no special characters . Have not found rect to polar etc.

These use to be on the key board or at least be able to make a costume soft key menu. I will give it a chance but first impressions confusing.. Must be made for school kids. I think I wasted my money . I own a 41,48,15,50,49,33. So I guess I am an hp purest.
