MDX Sine Function

Can I use the sine function within MDX? I woul开发者_StackOverflow社区d like to know the sine of a measure.

You can call into the VBA assembly in SSAS, you'll notice it in the SSAS Server assemblies folder.

Full list of VBA functions is here: http://www.ssas-info.com/analysis-services-articles/50-mdx/2075-vba-functions-in-as2005-mdx

Alternatively you could write your own CLR routine, and call that: http://geekswithblogs.net/dotNETPlayground/archive/2007/12/20/117869.aspx

EDIT: It looks like I've assumed you're on MS Analysis Services...If you are this should work, otherwise retag with your exact version?
