Hmm it is a HP48, isnt it? It can evaluate expressions in standard notation. I believe to remember that it is done by enclosing the expression in simple quotes. That was in the HP28; the HP48 had, I believe, some way to conmute between RPN and standard, beyond the quotes. But I can be wrong here.
The HP48 was supossed to be, time ago, the culmination of calculators. It was the combination of HP-41 plus HP-28. As the 41, it had the possibility of reading IE3 data, HPIB bus interfaces, etc. As the 28, it was able to do analitical calculus, derivatives, Taylor series expansion and such.
