Modulus arithmetics

  • To: mathgroup at smc.vnet.net

A mathematician colleague of mine needs to make
computations with integers modulus a prime number.
He told me that he gave a look at Mathematica, but
that he rejected it because it seemed to him that
Mma is very inefficient at that kind of calculations.

According to him, the calculations are made with
full integers throughout, and reduced modulus p only in the
end, with a big waste of time and memory.

I think he tried with version 2.2.

I am a long-time Mma user, but I have never used
Modulus myself. Can anyone confirm with me if
my colleague is right on this one?

Thanks in advance.

Gianluca Gorni
