Data.Deka.Pure

Pure interface to floating-point decimals.

Floating point operations are, in fact, performed in the IO monad because they are carried out through the FFI. However, the functions have no observable side effects, so this module uses unsafePerformIO to allow you to perform the computations in a pure function. This module is Trustworthy for Safe Haskell purposes. If you do not Trust me, use Data.Deka.IO, which is Safe for Safe Haskell purposes.

This module also re-exports everything in Data.Deka.IO.

Many functions in this module clash with Prelude names, so you might want to do

 import qualified Data.Deka.Pure as D
