scientific: Numbers represented using scientific notation

[ bsd3, data, library ] [ Propose Tags ]

Data.Scientific provides the number type Scientific. Scientific numbers are arbitrary precision and space efficient. They are represented using scientific notation. The implementation uses a coefficient c :: Integer and a base-10 exponent e :: Int. A scientific number corresponds to the Fractional number: fromInteger c * 10 ^^ e.

Note that since we're using an Int to represent the exponent these numbers aren't truly arbitrary precision. I intend to change the type of the exponent to Integer in a future release.

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
