Mathematics has some need to work with really very big numbers. That is 
whenever you try to disprove a hypothesis like e.g. the Rieman hypothesis by 
experimentally searching for a case where it does not hold.

That is nothing I am doing, but it to my mind when I thought about where to 
use exponents bigger than int32.

Is there any reason not to make the exponent type a template parameter so that 
the user can chose arbittrarily instead of trying to anticipate future uses of 
the library?
