Ursala (UniveRSal Applicative LAnguage) is a functional programming language suitable for scientific and numerical computation. It began in 1996 as a personal tool kit to assist its author at certain practical problems in CAD applications and mathematical finance, but it is now mature enough and adequately documented for general distribution.
The current release (December 2009) features some notable enhancements, namely a signed integer primitive type, improved reification operators, and various improved implementations of standard library functions. The compiler is smaller and in some cases faster than the previous version. Work is in progress for future releases on regular expression handling and more convenient operator overloading.
I would be grateful for feedback from anyone who finds this software interesting or useful, at the address ursala-support@basis.uklinux.net. This project is entirely a volunteer effort. There are many possibilities for collaboration or further contributions.
