ciaaw is a Fortran library providing the standard and abridged atomic weights, the isotopic abundance and the isotopes' standard atomic weights. The data are taken from http://ciaaw.org. C API allows usage from C, or can be used as a basis for other wrappers. Python wrapper allows easy usage from Python.

What have been implemented:

• SAW: Standard Atomic Weights.
• ICE: Isotopic Composition of the Element
• NAW: Nuclides Atomic Weight.

To use ciaaw within your fpm project, add the following to your fpm.toml file:

    [dependencies]
    iapws = { git="https://github.com/MilanSkocic/ciaaw.git" }

gcc>=10.0
gfortran>=10.0
fpm>=0.7
stdlib>=0.5

A Makefile is provided, which uses fpm, for building the library.

• On windows, msys2 needs to be installed. Add the msys2 binary (usually C:\msys64\usr\bin) to the path in order to be able to use make.
• On Darwin, the gcc toolchain needs to be installed.
