This library provides modules for some commonly used algorithms in scientific computing. Many of the modules have been ported to kForth from the Forth Scientific Library (FSL). The original FSL modules were written for Forth systems which use a separate floating point stack. The kForth versions of these modules, in addition to being modified for a unified data/fp stack, have also been revised and improved in some aspects, most notably with regard to the test code.
