+%description
+"Data.Scientific" provides the number type 'Scientific'. Scientific numbers are
+arbitrary precision and space efficient. They are represented using
+<http://en.wikipedia.org/wiki/Scientific_notation 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:
+
+* A 'Scientific' is more efficient to construct. Rational numbers need to be
+constructed using '%' which has to compute the 'gcd' of the 'numerator' and
+'denominator'.
+
+* 'Scientific' is safe against numbers with huge exponents. For example:
+'1e1000000000 :: 'Rational'' will 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 ''RealFloat's' (like: 'Double' or 'Float') will
+always be bounded by the target type.
