Calculator model with mod function? I'm wondering does anyone know of a scientific calculator with a mod function?
In C# this is shown as follows (just in case there are any other mods that a mathematical non-savant such as myself wouldn't be aware of)
5 % 4 = 1
I've looked through the most common ones on the web but the function is either not in the list or not present.
I have a little bit of a bias towards Casio calculators as that's what I'm familiar with but will accept any suggestions that can be currently purchased.

 A: HP : buy a hewlett packard calculator. the model HP-35S contains hundreds of functions. 
there is a description here ; http://www.shopping.hp.com/product/calculator/Scientific/1/storefronts/F2215AA%2523ABA;HHOJSID=FW7TNQVJMqHh075qvYbPbRvjvx2K1ybHFyYXGDY9Vr8kpqFlknwg!492383249
The 32Sii used to have a button just for that, on the other hand the
HP35s is programmable and you can most probably do it easily. 
A: Virtually every graphing calculator made in the recent past has a mod function.  Many scientific calculators do as well, though the documentation is often lacking.
A: GeoGebra has a Mod[a,b] command eg
http://web.geogebra.org/?command=Mod[5,4]
If you want to define it to use as a function you can do

mod(x, y) = y (x / y - floor(x / y))

and then use that, eg
http://web.geogebra.org/?command=mod(x,y)=y(x/y-floor(x/y));mod(5,4)
A: You can calculate mod on any calculator with this  algorithm:
Example 27 / 6 = 4.5
27 / 6 = 4.5
4.5 - 4 = 0.5  Get the fractional part
6 * 0.5 = 3   Mul the denominator and fraction 
27 mod 6 = 3
Works every time. 
A: There is a mod function in TI NSpire and any graphing calculator:
Syntax:  mod(number to divide, modulus (divisor)) 
E.g.  mod(35^51, 319) Enter yields 167
A: The TI-36x pro has a mod button under the Math menu.
