Comments on: When is C# 2.0 not equal to C# 2.0? http://www.christec.co.nz/blog/archives/86 Development for a mobile world - Making a quality platform one application at a time Fri, 12 Mar 2010 05:38:21 -0600 http://wordpress.org/?v=2.8.5 hourly 1 By: Christopher Fairbairn http://www.christec.co.nz/blog/archives/86/comment-page-1#comment-10626 Christopher Fairbairn Thu, 07 Aug 2008 22:22:42 +0000 http://www.christec.co.nz/blog/archives/86#comment-10626 It was pointed out to me recently that my comments about their being no Sin or Cos functions within the System.Math class of the .NET Micro Framework BCL is slightly confusing. Although they are not present within <a href="http://msdn.microsoft.com/en-us/library/cc318405.aspx" rel="nofollow">System.Math</a> there are forms of these functions within the .NET Micro Framework specific <a href="http://msdn.microsoft.com/en-us/library/cc318395.aspx" rel="nofollow">Microsoft.SPOT.Math</a> class. For example you can find the <a href="http://msdn.microsoft.com/en-us/library/cc319420.aspx" rel="nofollow">documentation for the Sin method</a> on MSDN. What I was trying to infer in my original post about the lack of Sin and Cos methods was code portability with source code originally designed for other versions of the .NET Framework. The reason why Sin is located within a different class on the .NET Micro Framework is due to API incompatabilities. You will notice from the documentation that the .NET Micro Framework version works with integer parameters measured in degrees, while the other versions of the .NET Framework deal with floating point parameters measured in radians. This means porting code is not as simple as changing your using statement.
