RPN #408

Open kgaler opened 2 years ago

kgaler commented 2 years ago

I've been using HP calculators since the 70's so I'm much more comfortable in the RPN mode. In trying to use Qalculate I must be missing something. I haven't been able to enter a simple expression with a negative exponent such as this. 2.3e-6 HP calculators have a "change sign" key to differentiate it from the minus key to change the sign.

How do I do this?

Regards

Currently the way to enter 2.3e-6 in RPN mode with "Use keyboard keys for RPN" enabled, is to do 2.3 ENTER 6 NEGATE EXP (or E ENTER). A possible simple solution would be to change the behaviour when the last character is e (now implemented).
