Module documentation for 1.0.2.0

Depends on 1 package(full list with versions):
ghc-prim

This package provides the low-level implementation of the standard Integer type based on the GNU Multiple Precision Arithmetic Library (GMP).

This package provides access to the internal representation of Integer as well as primitive operations with no proper error handling, and should only be used directly with the utmost care.

1.0.1.0 July 2017

  • Bundled with GHC 8.2.1

  • Optimize minusInteger

  • Fix the right-shift operation for negative big integers (fixes GHC #12136)

0.5.1.0 Feb 2014

  • Bundled with GHC 7.8.1
