qd-1.0: qd.cabal

Name:                 qd
Version:              1.0
Synopsis:             double-double and quad-double number type via libqd
Description:
    This package supports both a double-double datatype (approx. 32 decimal digits)
    and a quad-double datatype (approx. 64 decimal digits), using libqd (which is
    implemented in C++ with C and Fortran wrappers).  To compile this package you
    need libqd to be installed.
    .
    @'Numeric.QD.DoubleDouble.DoubleDouble'@ and @'Numeric.QD.QuadDouble.QuadDouble'@
    are strict tuples of @CDouble@s, with instances of:
    @'BinDecode'@, @'DecimalFormat'@, @'Eq'@, @'Floating'@, @'Fractional'@, @'Num'@,
    @'Ord'@, @'Read'@, @'Real'@, @'RealFrac'@, @'Show'@, @'Storable'@, @'Typeable'@.
    .
    Additional note: libqd depends on 64bit doubles, while some FPU architectures
    use 80bit.  When using the Unsafe modules this might cause erroneous results;
    the Safe modules (used by the instances above) set and restore the FPU flags
    in foreign code to avoid race conditions from pre-emptive Haskell threading.
    .
    The @'RealFloat'@ instances have been removed in this release as they were
    mostly broken: @'RealFloat'@ semantics are for fixed-precision numbers.
