General Development This article discusses a small-scale benchmark test run on nine modern computer languages or variants: Java 1.3.1, Java 1.4.2, C compiled with gcc 3.3.1, Python 2.3.2, Python compiled with Psyco 1.1.1, and the four languages supported by Microsoft's Visual Studio .NET 2003 development environment: Visual Basic, Visual C#, Visual C++, and Visual J#. The benchmark tests arithmetic and trigonometric functions using a variety of data types, and also tests simple file I/O. All tests took place on a Pentium 4-based computer running Windows XP. Update: Delphi version of the benchmark here.

non-IEEE compliant

Important Note: Pentium trig functions are not IEEE compliant. GCC's trig functions are. If you need accuracy you cannot unse the built in intel trig functions. The MS compilers in this test used the built in trig functions. You can di this with GCC; however, you have to specify it in the code. I seriously doubt this was done.
Bottom line: The trig functions in this test are not computing the same thing. The MS results will give 5-6 digits of precision. GCC's will be correct to 12+. *HUGE* difference.
