The Measures Package provides dimensioned numbers (i.e. numbers with dimensional units, short: dim-numbers) for Common Lisp.

The software was originally written by Roman Cunis, Hamburg, Germany and then maintained by Ralf Möller. See: http://www.cs.cmu.edu/Groups/AI/util/lang/lisp/code/syntax/measures/0.html

This version is taken from LOOM, which has various extensions and defines many dimensional units. See: http://www.isi.edu/isd/LOOM/

This product includes software developed by and/or derived from the LOOM Project (http://www.isi.edu/isd/LOOM/LOOM-HOME.html) to which the U.S. Government retains certain rights.

Rainer Joswig ([email protected] , 2017) removed some support for older versions of Common Lisp, fixed some problems and updated the system definition.

System declarations for ASDF and LispWorks are provided.

The software still uses a logical pathname "MEASURES". It is set up by loading the file "measures-sysdcl.lisp".

This version assumes a variant of ANSI Common Lisp.

Load in LispWorks:

(load "measures-sysdcl.lisp") (compile-system :measures :load t)

Load in Clozure CL:

(require "ASDF") (load "measures-sysdcl.lisp") (asdf:compile-system "Measures") (asdf:load-system "Measures")

Use:

CL-USER 2 > (ms:dim* #M10kg #M10min) #M6000kg.s
