Modular exponent returns wrong answer

[Former user]

mod(2^300;3) = 0

No power of two is divisible by 3. This is probably a rounding issue. I think it would be best if SpeedCrunch didn't return anything at all when one of mod's inputs is beyond a certain threshold.

I get the following on latest development code:

mod(2^300;3)
= 1

What version are you on?
