# integer-map This is the CHICKEN version of the SRFI 224 Scheme library providing fixnum (integer) maps. For the (more) portable version, see the [SRFI repo](https://github.com/scheme-requests-for-implementation/srfi-224). Fixnum maps (fxmappings) are implemented using the big-endian radix (Patricia) tree structure described by Chris Okasaki and Andrew Gill in ["Fast Mergeable Integer Maps"](http://ittc.ku.edu/~andygill/papers/IntMap98.pdf). These provide fast lookup and set-theoretical operations. # Copying This is free and open-source software released under the MIT/X license.
