The scientific package

[Tags: bsd3, library]

Data.Scientific provides a space efficient and arbitrary precision scientific number type.

Scientific numbers are represented using scientific notation. It uses a coefficient c :: Integer and a base-10 exponent e :: Int (do note that since we're using an Int to represent the exponent these numbers aren't truly arbitrary precision). A scientific number corresponds to the Fractional number: fromInteger c * 10 ^^ e.

The main application of Scientific is to be used as the target of parsing arbitrary precision numbers coming from an untrusted source. The advantages over using Rational for this are that:

 > read "1e1000000000" :: Scientific
