Line 39: Plus, what's "mathematical purity" anyway? [[Special:Contributions/213.243.143.189\|213.243.143.189]] ([[User talk:213.243.143.189\|talk]]) 20:14, 23 September 2008 (UTC) : Mathematical purity, that is to call a programming "pure", means that application of functions are free from side-effects. They don't change any state except the ones within their scope. A typical example of non-pure function is random number seeding and generation. == Bill Joy ==
