Excuse my English I think, we could just segregate tokens for decimal and real float and make them interoperable. Motivation: Most of us works with business databases - all "floats" are really decimals, algebraic operations should work without float inconsistency and those operations rare so speed is not important. But some of us use floats for speed in scientific and multimedia programs.
with from __future__ import Decimal we could: a) interpret regular float constants as decimal b) interpret float constants with suffix 'f' as float (like 1.5f 345.2e-5f etc) c) result of operation with decimal operands should be decimal >>> 1.0/3.0 0.33333333333333333 d) result of operation with float operands should be float >>> 1.0f/3.0f 0.33333333333333331f e) result of operation with decimal and float should be float (decimal converts into float and operation perfomed) >>> 1.0f/3.0 0.33333333333333331f >>> 1.0/3.0f 0.33333333333333331f _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
