%description

Data.Scientific provides a space efficient and arbitrary precision scientific
|
||||
number type.
|
||||
'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'.
|
||||
|
||||
This package provides the Haskell %{pkg_name} libraries.
|
||||
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.
|
||||
|
||||
%package -n ghc-%{pkg_name}-devel
|
||||
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.
