These PLIST files have been autogenerated by mk/haskell.mk using
HS_UPDATE_PLIST=yes during a bulk build. They will help to track changes
to the packages. The Haskell packages didn't have PLIST files because
their paths contained package hashes. These hashes are now determined by
mk/haskell.mk, which makes it easy to generate easy to read PLIST files.
0.3.6.2
* Due to a regression introduced in 0.3.4.14 the RealFrac methods and
floatingOrInteger became vulnerable to a space blowup when applied
to scientifics with huge exponents. This has now been fixed again.
0.3.6.1
* Fix build on GHC < 8.
0.3.6.0
* Make the methods of the Hashable, Eq and Ord instances safe to use
when applied to scientific numbers coming from untrusted
sources. Previously these methods first converted their arguments to
Rational before applying the operation. This is unsafe because
converting a Scientific to a Rational could fill up all space and
crash your program when the Scientific has a huge base10Exponent.
Do note that the hash computation of the Hashable Scientific
instance has been changed because of this improvement!
Thanks to Tom Sydney Kerckhove (@NorfairKing) for pushing me to fix
this.
* fromRational :: Rational -> Scientific now throws an error instead
of diverging when applied to a repeating decimal. This does mean it
will consume space linear in the number of digits of the resulting
scientific. This makes "fromRational" and the other Fractional
methods "recip" and "/" a bit safer to use.
* To get the old unsafe but more efficient behaviour the following
function was added: unsafeFromRational :: Rational -> Scientific.
* Add alternatives for fromRationalRepetend:
fromRationalRepetendLimited
:: Int -- ^ limit
-> Rational
-> Either (Scientific, Rational)
(Scientific, Maybe Int)
and:
fromRationalRepetendUnlimited
:: Rational -> (Scientific, Maybe Int)
Thanks to Ian Jeffries (@seagreen) for the idea.
0.3.5.3
* Dropped upper version bounds of dependencies because it's to much
work to maintain.
0.3.5.2
* Remove unused ghc-prim dependency.
* Added unit tests for read and scientificP
0.3.5.1
* Replace use of Vector from vector with Array from primitive.
0.3.5.0
* Export scientificP :: ReadP Scientific

0.3.4.15
* Fix build for base < 4.8.
0.3.4.14
* Some minor performance improvements.
0.3.4.13
* Support criterion-1.2
0.3.4.12
* Support base-4.10
0.3.4.11
* Support tasty-ant-xml-1.1.0
0.3.4.10
* Tighten lower bound on vector from 0.5 to 0.7 because building with
vector < 0.7 results in a build error.
* Move the internal modules Math.NumberTheory.Logarithms and
GHC.Integer.Logarithms.Compat to their own package
integer-logarithms so other people can share that code.
0.3.4.9
* Support QuickCheck-2.9.
0.3.4.8
* Make bytestring-builder's installation conditional based on a Cabal flag.
0.3.4.7
* Unconditionally export Data.ByteString.Builder.Scientific. The
bytestring-builder cabal flag has been removed. Depend on
bytestring-builder for backwards compatibility for GHC < 7.8.
0.3.4.6
* Made toDecimalDigits more similar to floatToDigits
Previously:
toDecimalDigits 0 == ([0],1)
Now:
toDecimalDigits 0 == ([0],0)
Because:
Numeric.floatToDigits 10 (0 :: Double) == ([0],0)
* Introduce a special case for 0 in fromFloatDigits
fromFloatDigits 0 = 0
This should fix https://github.com/bos/aeson/issues/369
0.3.4.5
* The following are all a courtesy of Oleg Grenrus (phadej):
* Support GHC-8.0.1
* Support binary-0.8
* Enable Travis continuous integration
0.3.4.4
* Improved performance of toDecimalDigits by 13%.
0.3.4.3
* Fix build with integer-simple.
0.3.4.2
* Fix build on GHC-7.4. Courtesy of Adam Bergmark..
0.3.4.1
* Fix build on GHC-7.0.4
0.3.4.0
* Added fromRationalRepetend & toRationalRepetend for safely
converting from and to rationals which have a repeating decimal
representation like:
1 % 28 = 0.03(571428).
* Added a Binary instance.
* Various performance improvements.
* Support vector-0.11
* Support tasty-0.11
* Support criterion-1.1.0.0
0.3.3.8
* Support QuickCheck-2.8.
0.3.3.7
* Fixed both the
Prelude Data.Scientific> reads "0.0" :: [(Data.Scientific.Scientific,String)]
[(0.0,".0"),(0.0,"")]
problem and the
read " 8" :: Scientific fails, while read " 8" :: Double succeeds
problem. Courtesy of neongreen.
0.3.3.6
* Fixed bug in the x / y method for Scientific. Since I was using the
default implementation: `x * recip y` the operation would diverge
when `recip y` had an infinite decimal output. This shouldn't happen
when the result of / is finite again. For example: 0.6 / 0.3 should
yield 2.0.
This is now fixed by using the following implementation:
`x / y = fromRational $ toRational x / toRational y`
changelog:
0.3.3.5
* Fixed bug when converting the Scientific:
`scientific 0 someBigExponent` to a bounded Integral using toBoundedInteger
or to a bounded RealFloat using toBoundedRealFloat.
If someBigExponent was big enough to trigger the big-exponent protection
the beforementioned functions didn't return 0.
This is fixed by explicitly handling a coefficient of 0.
changelog:
0.3.3.4
* Relax upper version bounds of base and deepseq
for the test suite and benchmarks.
0.3.3.3
* Add support for `deepseq-1.4`.
0.3.3.2
* Fix parsing of empty digit string (#21).
changelog:
0.3.3.0
* Add the isFloating or isInteger predicates.

* Add the toRealFloat' and toBoundedInteger functions.

0.3.2.2
* Enable package to link with integer-simple instead of
integer-gmp using the -finteger-simple cabal flag.
Courtesy of @k0ral.
0.3.2.1
* Parameterize inclusion of the Data.ByteString.Builder.Scientific
module using the bytestring-builder flag. Disabling this flag
allows building on GHC-7.0.4 which has bytestring-0.9 installed
by default.
0.3.2.0
* Add the floatingOrInteger function
* Fix build on GHC-7.0.4
* More efficient and better behaving magnitude computation
* Lower the number of cached magnitudes to 324 (same as GHC.Float)
0.3.1.0
* Don't normalize on construction but do it when pretty-printing
instead. Also provide a manual normalize function.
* Improve efficiency of toRealFloat
* Added note about caching magnitudes
* Dropped dependency on arithmoi
* Make benchmark easier to build
* Add junit XML output support (for Jenkins)
0.3.0.2
* Lower the minimal QuickCheck version.
* Make sure sized exponents are generated in the QuickCheck tests.
0.3.0.1
* Fix build for bytestring-0.10.0.*
0.3.0.0
* Fix a DoS vulnerability that allowed an attacker to crash the
process by sending a scientific with a huge exponent like
1e1000000000.
* Fix various RealFrac methods.
* Cache some powers of 10 to speed up the magnitude computation.
* Normalize scientific numbers on construction.
* Move the Text Builder to its own module &
provide a ByteString builder
* Added more documentation
packaged for wip.
A Scientific number is an arbitrary-precision floating-point number
represented using scientific notation.
A scientific number with coefficient c and base10Exponent e corresponds to
the Fractional number: fromInteger c * 10 ^^ e
Its primary use-case is to serve as the target of parsing floating point
numbers. Since the textual representation of floating point numbers use
scientific notation they can be efficiently parsed to a Scientific number.
