+synopsis:           Numbers represented using scientific notation
+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.
