There's a library for .NET that does financial calculations or implements Excel-like functions?

I'm working in a ASP.NET project wich is suposed to do several financial calculantions involving potentiations, nth roots, etc. For this first operations, I can easily solve the problem using Math. But, for calculating work days - like Excel, or monthly loan payment, interest rates, etc. - like HP 12C, there is a library that i开发者_StackOverflow社区mplements these functions? Thanks!

You might want to check out the Excel Financial functions for .NET

This is a .NET library that provides the full set of financial functions from Excel. The main goal for the library is compatibility with Excel, by providing the same functions, with the same behaviour. Note though that this is not a wrapper over the Excel library; the functions have been re-implemented in managed code so that you do not need to have Excel installed to use this library.

The Microsoft.VisualBasic assembly in .NET 4.0 also exposes some financial functions. Even though they are ostensibly VB 4.0 keywords there is nothing stopping you from referencing them from a C# or other CLR language project (I'm assuming they are CLR-compliant).

Have you looked at Open source or free financial analysis programs/libraries
