Project name: FloatPerfTest
Date of creation: 5.6.2010
Platform: C++ and C#
Licence: GPL
Sources: Yes
Description: FloatPerfTest is a simple floating point benchmark software. It calculates values in the mandelbrot fractal set and measures how long it took. There are 3 implementations: C++, C# .NET 2 and C# .NET 4 (C# code is identical, just a different runtime). The code was done/compiled using Visual Studio 2010 Express. The C++ release build has fast floating point maths and other optimizations turned on. Results on my computer:

CPU: Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz (4 CPUs), ~2.4GHz

FLOAT:
======
C++(rel): Amount in set: 1508359/16000000, calculation took 27.498001 seconds
C++(deb): Amount in set: 1508326/16000000, calculation took 41.105000 seconds
C#4: Amount in set: 1508326/16000000, calculation took 37,611 seconds
C#2: Amount in set: 1508326/16000000, calculation took 34,926 seconds
