Hello,

I have a question regarding integers arithmetics.

I am wondering if any languages or application heavily rely on
modulo arithmetics:

Given the range [0,50], the basic operation are
redefined as follow:

a op b => ( a op b ) % 51

e.g.:
27+30 = 57 % 51 = 7
12*12 = 144 % 51 = 44

All I can think about is error corection and encryption. Any other purpose ?

Christian.
