c8 is designed as an easy-to-use big number (unlimited precision) library that has no dependencies other than the standard C++ libraries provided with gcc or clang.

Number Types

c8 provides supports for three primary classes of numbers:

• c8::natural provides natural numbers.
• c8::integer provides integers.
• c8::rational provides rational numbers.

Between these 3 it's possible to represent all of the interesting numbers that a computer can directly represent, with floating point numbers are a subset of the set of rational numbers. By using rationals instead of floating point it's also much easier to avoid some types of computational error.
