Add +', *', -', inc', dec', that do exactly what their counterparts do except when given integers of long or smaller, in which case they will not auto-promote but instead throw on overflow, and can return primitives. Return primitive doubles on all ops involving primitive doubles Box on long ops only after checking for overflow Change = to include type of boxed numbers (and collections thereof). Use == for inter-type numeric equivalence. 2010-06-17T17:12:59Z Rich Hickey richhickey@gmail.com 2010-06-17T17:12:59Z urn:sha1:8b849574ca1186c65124b43da8de6be6bace3f96 tighten up numeric comparisons 2010-06-17T14:01:10Z Rich Hickey richhickey@gmail.com 2010-06-17T14:01:10Z urn:sha1:e526bb845d76dd920df335dedd796b8f44ab4b4e remove unchecked-inc from amap, areduce 2010-06-16T12:09:54Z Rich Hickey richhickey@gmail.com 2010-06-16T12:09:54Z urn:sha1:26e50c31e4fd822df1c4a385b5f57f09175ebb52 Unify numeric semantics around longs, with throw on overflow. Allow numeric literals to be primitive initializers. Canonicalize boxing of integers, if it fits in int, is Integer, else Long, thus primitive coercions can't be used to get particular boxed types, use Long/valueOf etc. Ask for BigIntegers if you want arbitrary precision, new literal number format - append 'N' for BigInteger. BigIntegers do not reduce automatically, are contagious. New particular names for unchecked ops - unchecked-xxx-int or unchecked-xxx-long. You should need far fewer hints for primitive perf, and avoid int casts and any casting of numeric literals, see: 2010-06-16T03:13:05Z Rich Hickey richhickey@gmail.com 2010-06-16T03:13:05Z urn:sha1:6ab3e4cd672092823a04c944210a23c29142785d http://gist.github.com/440102
