libinum is a library that implements several numerical algorithms.
One of the its main originalities is that it supports both fixed and arbitrary precision floating point numbers. Fixed precision floating point numbers have a predetermined number of digits, whereas arbitrary precision floating point numbers can have as many digits as needed. Numerical truncation errors can, therefore, be controlled for arbitrary precision floats. However, manipulating them is slower than fixed precision floats. If computational precision is more important than speed, then arbitrary precision floats may be used, whereas if speed is more of an issue, then fixed precision floats may be preferable. The functions provided by libinum can be used in both cases.
