Picomath is a collection of small math functions inspired by John D. Cook's Stand-alone code for numerical computing. It is not compiled into a library in the usual sense (that is, something you can link to). Rather, the functions are presented as standalone snippets of code.


The picomath library is in the public domain. Do whatever you want with it, no strings attached. Use at your own risk.


Picomath provides the following functions:


The functions are implemented in the following languages:


The picomath library is organised into subdirectories, with each language in a subdirectory. Each function (or group of interrelated functions such as Gamma and Log Gamma) are implemented in one source file. Each source file is designed with minimal dependencies, so it can be included directly into a project as is, or copy and pasted into other code.

Test Suite

The test suite consists of two parts:

To build the tests:

    $ scons

To run the tests:

    $ python test.py

The expected output is:

    Checking ada... ok
    Checking cpp... ok
    Checking csharp... ok
    Checking d... ok
    Checking erlang... ok
    Checking go... ok
    Checking haskell... ok
    Checking java... ok
    Checking javascript... ok
    Checking lua... ok
    Checking pascal... ok
    Checking perl... ok
    Checking php... ok
    Checking python... ok
    Checking ruby... ok
    Checking scala... ok
    Checking scheme... ok
    Checking tcl... ok

The top level test.py runs each language-specific test.* in turn, communicating with the implementation using standard input and output. A simple text-based protocol is used to execute functions and return results.
