new Exact Arithmetic mode
/!\ built in firmware 2021
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 or without pressing the [a b/c] key Also numworks has an important feature is that it shows the result in approximate and exact form sqrt(24) [enter] 2*sqrt(6) ~= 4.898979...

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
