128-bit integer

int128 and uint128 are very similar classes for operations over 128-bit numbers.

Unlike other large number classes, you can work with these just like with other P.O.D. types (for example store and load from files using fwrite/fread). Internal representation of these is correct 128-bit little-endian integer.

Features:

Implemented are all relevant operators and following abilities:

• Classes can parse up to 128-bit number from classic C string in decimal, octal (0...) or hexadecimal (0x...) notation. Numbers can be negative.
• Convert number to string (with radix from 2 to 37).
• Compute division and remainder in single operation (div method).
• Classes support GNU G++ operators <? a >?.

Future:

• Consider implementation of operators for conversion to intrinsic types.
• Rewrite division operation
• Remove the bit method used only in division.
