Calculators with mod and custom functions

  1. Sep 3, 2013 #1
    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?

    My HP-50g has a mod function.

    Otherwise, if you have the floor function and can program functions you can use [itex]a \mathop{\mathrm{mod}} b = a - b\left\lfloor\frac{a}{b}\right\rfloor[/itex]. (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.
