new Exact Arithmetic mode
Hello
The new firmware of the Tinspire series, offers a third mode: the Exact Arithmetic mode, I think that this characteristic is essential in the numeric mode of the hpprime without entering the CAS mode Also numworks has an important feature is that it shows the result in approximate and exact form, (good point to clone)

RE: new Exact Arithmetic mode
Hi!, compsystems :
With the HP PRIME, you too can obtein, but in aproximate mode with (a b/c).

RE: new Exact Arithmetic mode
but the idea is automatic form without using commands or extra keystrokes, as seen in the capture of the numWorks calculator, shows the output in two formats
sqrt(24) [enter] 2*sqrt(6) ~= 4.89...

Which version is that taken from? Quote:Also numworks has an important feature is that it shows the result in approximate and exact form, (good point to clone) It does seem to get better. It was quite poor in some areas when it first came out, but that looks like a nice feature! — Ian Abbott

RE: new Exact Arithmetic mode
The TIEDUCATION group, when it launched the tinspire series and ported TIbasic of the ti89 series to the TINspire, did not incorporate pixel commands, because according to them, the students would dedicate themselves to making games. according to several authors,programming games, you can develop algorithmic thinking and even mathematical thinking.
They also said that very few teachers request the complete tibasic catalog of the ti68k, but after the numWorks calculator, it launched the first calculator with microPython, plus the handling of pixels, TI added the commands for managing pixels on TInspire series and an external device with uPython for the TI84 series, the suggestions of the users did not weigh, but the content of the apps of its competitors.
