903 CALCPLUS - improved scientific calculator

MartinZ · 06-29-2011, 06:39 AM

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

Thanks !

Seems to work well in 602
I have noticed that when you do, for example :
4 x 5 = 20, then you type a number, it replaces the previous result
But when you do the same thing with a conversion from foot to meters, it append the number to the result, which I suppose could be a bug.

Yep: This behaviour occurs for all other unary operations as well (like sqr, sin, sqrt) .

It is not really important, cause it does not make much sense to press a number key after a finshed operation at all.
But i changed this already.

Cheers,

thank you for this quick update !

Hi,

can someone try, if the appended version of CALCPLUS works for the
"302" EReader?

I also append a bugfixed version of the 90x/60x version (a buffer was too small and perhaps a crash could occure for some languages)

I haven't got much feedback for calcplus yet. Does it work for all of you?

Hi Martin

The 302-Version is working fine!! Thanks for this!

Hi

Calcplus works fine on 912.
Worth mentioning feature : calcplus takes the whole screen. And not only a 6xx size portion of the screen, which is the case of most applications that run on both 6xx and 9xx series.
