math-functions: collection of tools for numeric computations

This package provides collection of various tools for numeric computations. Namely:

  • Number pure haskell implementations of special function which are used in statistical and numerical computing.

  • Compensated summation (Kahan summation) which allows to

  • Root finding for functions of single real variable

  • Series summation

  • Functions for comparing IEEE754 numbers

Where possible, we give citations and computational complexity estimates for the algorithms used.

Get involved!

Please report bugs via the github issue tracker.

  • git clone https://github.com/haskell/math-functions.git
