| TI-Nspire CAS iOS App: Fractional Approximations |
* TI-NSpire CAS iOS App:
this should be similar to the TI-Nspire CAS handheld calculators, x→approxFraction(5.E-14)
* Casio Classpad fx-CP400: fractional approximation used by tofrac(approx(x))
* HP Prime (firmware 10077), pressing [a b/c] after the
number is entered
