Modern (axiomatic) mathematics, does not use a fixed standard vocabulary for formal terms.
Instead, formal terms are being defined /specifically/ for each theory by axioms. Informal terms are used in explanations of formal texts and might be somewhat vague.
While ISO 2382 might define »variable« somehow, in programming, the term also is context-dependent: For example, in »Java Language Specification, Third Edition« a »variable« is what in »ISO/IEC 14882:2003(E)« is an »object«.
For successful communication you need to agree on a common vocabulary with your dialog partner. Often you can not just take it for granted. Received on Fri Feb 15 2008 - 00:22:59 CET
