TI-36x PRO Equivalent - Printable Version +- HP Forums (https://www.hpmuseum.org/forum) +-- Forum: HP Calculators (and very old HP Computers) (/forum-3.html) +--- Forum: General Forum (/forum-4.html) +--- Thread: TI-36x PRO Equivalent (/thread-8310.html) TI-36x PRO Equivalent - Chris. - 05-06-2017 05:16 PM Does HP make a SCIENTIFIC Calculator with a similar display and features as the TI-36x PRO? One feature I want is the outputs to display as simplified values. For example Sqrt(5^2+6^2) = Sqrt(61) not 7.8102.... RE: TI-36x PRO Equivalent - pier4r - 05-06-2017 08:49 PM as far as I know you need the CAS for that, so 49g+, 50g and Prime (and maybe some model before with additional libraries IIRC). RE: TI-36x PRO Equivalent - Chris. - 05-07-2017 01:59 AM I Don't actually mean CAS capability on a scientific calculator. I mean that: Entering the square root of 5 squared plus 6 squared would return Sqrt(61) instead of the decimal approximation. some more examples are entering 65/4 would return 65/4 or entering 200/400 would return 1/2 and not 0.5. If there is a proper name for that feature would anyone state it please? Is the hp 300s+ the ti-36x pro or is it another calculator. Both have the multiview RE: TI-36x PRO Equivalent - pier4r - 05-07-2017 06:29 AM What you ask is done by the exact mode on the 50g, and it is using part of the case engine as far as I know. I don't think that system without a small Cas engine can do it on the hp side but here there are more experts so let's wait their suggestions. RE: TI-36x PRO Equivalent - Massimo Gnerucci - 05-07-2017 08:16 AM I would never trust a calculator giving Sqrt(5^2+6^2) = Sqrt(64) RE: TI-36x PRO Equivalent - Dani R. - 05-07-2017 05:23 PM QPI http://www.hpmuseum.org/software/qpi/42sqpi.htm can simulate this function on a HP42S RE: TI-36x PRO Equivalent - Chris. - 05-07-2017 06:03 PM I meant 61 where I put "64" in sqrt(64) answers, I fixed in edit. RE: TI-36x PRO Equivalent - thomasross - 05-07-2017 10:40 PM +1 for QPI, although I have only used it on the 48G family RE: TI-36x PRO Equivalent - BartDB - 05-07-2017 11:13 PM (05-06-2017 05:16 PM)Chris.

Many modern high end scientific calculators have a display mode that will attempt to display answers more accurately e.g. as fractions or surds (usually a button to change to floating point or a mode to always give floating point answers).

QPI tries to approximate a given number by a fraction or a term with logs and roots. This can be misleading. For instance, when set to 6 digit precision such a program may return "pi" even if the result of a calculation is simply 355/113 – and vice versa. The idea is not to have a number and then find a "nice" representation for it, but to display the exact result of a calculation (which can then be evaluated as a decimal approximation). Also consider that QPI would return the result of √(3²+4²) simply as "5" and not as √25. ;-) Dieter
