Projects / SpecialValue


SpecialValue is a C++ library that allows special numeric values to be represented accurately. This is useful for fractions that would normally be approximated as floating point, or numbers that are normally impossible to store, such as sqrt(-2).

Recent releases

        Release Notes: The functions exp, exp2, exp10, sin, cos, tan, cot, sinh, cosh, tanh, coth, and log are supported now. Some bugs have been fixed in sqrt.

        •  28 Jan 2004 13:17

          Release Notes: The interface has changed. This is a bad thing to do, but it was required by the Arithmos project, for which this library is developed after all. The internal representation was adapted such that the library now implements the ideas in the article "Universal semantics for computer arithmetic implementations" by B. Verdonk, J. Vervloet, and A. Cuyt, which has been submitted to TJCS.
