ChangeLog for Ump
-----------------
v0.8.6
( Everything here is backported from v0.9.0 as that version will take much more time to stabilize )
2007-04-16
Faster large integer multiplication, ~15%
Added function powMod which is used automatic when it's possible,
it handles -- a^b mod c -- (where a,b,c is integers) in a more efficient way
Faster faculty calculations, at least twice as fast below 92681!
Fixed so that e.g. 3 mod 1.2 gives error message "Unsupported datatype for mod" and not "Division by zero"
Fixed so that 0^0 equals to 1 and not in an error message
Small fixes in functions: factorize, isPrime, isMersenne
