new Exact Arithmetic mode
Hello

The new firmware of the Ti-nspire series, offers a third mode: the Exact Arithmetic mode, I think that this characteristic is essential in the numeric mode of the hp-prime 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)

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...

Hasn't the NSpire CAS always offered a choice between "Auto", "Exact", and "Approximate" calculation mode? But your screenshot looks different. Which version is that taken from?

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!

The new firmware (probably v5.0.0.0, a major release) is not out yet … it'll be out along with the new CX II (approximately at March 2019) and … frankly I'm not sure that will be more or less compatible with the "old" CX … let's wait and see Wink
Best,

RE: new Exact Arithmetic mode
The TI-EDUCATION group, when it launched the ti-nspire series and ported TI-basic of the ti89 series to the TI-Nspire, 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 ti-basic 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 TI-nspire series and an external device with u-Python for the TI84 series, the suggestions of the users did not weigh, but the content of the apps of its competitors.
