Hi folks,
i just created an improved (and thus more useable) version of what PB called a "scientific" (

) calculator.
Features:
- priority of "^" , "*", "+"
- parentheses / brackets for e.g. "3*(4+5)" etc.
- EXP
- "Eng" for engineering (E-03, E+06)
- several unit conversions
- asin, acos, atan (and not only "sinh")
Please try the appended beta.
(only tested for 903 so far, but could work for 902, 60X) as well.
Edit: Seems to work on all 90x/60x ! (of course having a stylus is quite useful for this.)
if all works, i submit source code as well.
have fun,
MartinZ
