It's the pi benchmark from bench.py. This is what I'm typically getting on a Core 2 Duo 3.16 GHz: Precision: 9 decimal digits float: result: 3.1415926535897927 time: 0.113188s cdecimal: result: 3.14159265 time: 0.158313s decimal: result: 3.14159265 time: 18.671457s Precision: 19 decimal digits float: result: 3.1415926535897927 time: 0.112874s cdecimal: result: 3.141592653589793236 time: 0.348100s decimal: result: 3.141592653589793236 time: 43.241220s Stefan Krah _______________________________________________ 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
