README
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. I intend to change this to Integer in the future!). 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:
A
Scientificis more efficient to construct. Rational numbers need to be constructed using%which has to compute thegcdof thenumeratoranddenominator.Scientificis safe against numbers with huge exponents. For example:1e1000000000 :: Rationalwill fill up all space and crash your program. Scientific works as expected:
> read "1e1000000000" :: Scientific
1.0e1000000000
- Also, the space usage of converting scientific numbers with huge exponents to
Integral's (like:
Int) or RealFloats (like:DoubleorFloat) will always be bounded by the target type.
