RPN to Algebraic and viceversa code

[Gilles]

Hi DarkKnight,

HP49-50 are marvelous calculators. The flag to toggle RPN<->Algebraic is -95

-95 SF -> Algebraic
CF(-95) -> Go to RPN mode

But in my opinion it's a bad idea to toggle this way. In fact all the algebraic mode of the 49-50g is a bad idea lol. I never use it.

If you want to use algebraic expression in RPN mode, just use the ' key. Ex :

'3*SIN(33)/25'
And the press EVAL ou ->NUM

You can also use EQW (i love this, it takes 5 mn to undestand how it works with the doc and then you can manipulate expressions so easily for all your life !) in RPN mode ;D In fact it's very easy tu use algebraic expressions in RPN mode.
