For me Python is useful to write code that gives *correct* results, allowing me to write it in a short & simple way, with quick debugging cycles (and for other purposes, like to write dynamic code, to use it as glue language to use libraries, to create quick GUIs, as scripting for data munging, etc). When I need more speed I use the D language, or Psyco, or C, etc.
Python 2.5 has string, unicode, long, int, float, and Decimal types. Python 3.0 reduces them to string (+ the byte type) int, float, and Decimal. So why not adopt the Decimal (IEEE 854) as the standard "float" for Python (if speed is a concern, than a mfloat type may be introduced, it's a "machine float", it's essentially the "float" of Python 2.5, operations between a float and a mfloat give a mfloat)? It can reduce some FP bugs, and avoid those 5.89 + 3.99 = 9.879999999999999 bugs that puzzle newbies, that are okay in a very fast low-level language like C++, but probably unfit for a high-level one :-) Bye, bearophile -- http://mail.python.org/mailman/listinfo/python-list
