Longs are too small!

[PsychoticPsymon]

So, here I am, working on number theory, thinking, "Ach, I hate doing aaaaalllllll this binomial expansion crud, I wish there was a program... "

Duh! Whipped it up in about an hour.

But than I try a daring exponent, something to the affect of 480505715157551513815415, long enough to throw an exception. Not enough space, o noes! What to do, what to do?

I wasn't sure if there was a way to declare a variable with a different memory allocation, larger than the big bad 64 I got.

Help is, as always, appreciated =)

Use the Decimal type:

Holds signed 128-bit (16-byte) values representing 96-bit (12-byte) integer numbers scaled by a variable power of 10. The scaling factor specifies the number of digits to the right of the decimal point; it ranges from 0 through 28. With a scale of 0 (no decimal places), the largest possible value is +/-79,228,162,514,264,337,593,543,950,335 (+/-7.9228162514264337593543950335E+28). With 28 decimal places, the largest value is +/-7.9228162514264337593543950335, and the smallest nonzero value is +/-0.0000000000000000000000000001 (+/-1E-28).

They are slower than other numerical types so should be avoided if not required, but if they are required then dive right in.
