Calculators with mod and custom functions

Click For Summary
SUMMARY

The discussion centers on the need for calculators that support the mod (remainder) function and allow users to input custom functions, such as f(x) = (x^2 + 3x + 2) mod 13. Participants recommend the HP-50g and HP48G+ calculators for their built-in mod functionality. Additionally, users can program custom functions using the TI-84+ by implementing the formula a mod b = a - b * ⌊a/b⌋. Perl programming is also suggested as a viable option for creating such calculations.

PREREQUISITES
  • Understanding of modular arithmetic and the mod function
  • Familiarity with programming concepts, particularly in Perl
  • Knowledge of calculator programming on TI-84+
  • Experience with polynomial functions and their evaluations
NEXT STEPS
  • Explore programming capabilities of the TI-84+ for custom functions
  • Learn Perl programming for mathematical computations
  • Research features of the HP-50g and HP48G+ calculators
  • Study modular arithmetic applications in programming
USEFUL FOR

Mathematicians, educators, students, and anyone interested in advanced calculator functionalities and custom mathematical computations.

Hi,
I need a calculator that have mod(remainder) function and that allows me to enter custom function, for example: f(x) = (x^2+3x+2)mod13 , and then quickly calculate the values of that function by entering different values for x.
Do you know any calculator that can do that?
Thanks

My HP-50g has a mod function.

Otherwise, if you have the floor function and can program functions you can use a \mathop{\mathrm{mod}} b = a - b\left\lfloor\frac{a}{b}\right\rfloor. (This is what I did with my TI-84+.)

Yeah... learn PERL and you can do that... or buy an HP48G+, that can do it.
