    Math parser/solver engine - Very cool, need testers

    Hi everyone,

    I've ported an enhanced a math parser from Leonardo Volpi to VB.NET. It's now a DLL library with support for custom functions, variables/constants, etc.

    If you don't know what a math parser is, here is a brief description:

    Computers threat strings as exactly that, strings. So a string like "5+2" has no actual mathematical meaning for a compiler/interpreter. So what this math parser does is return the result of that operation, i.e., "7". You can use much more complicated expressions, like:

    "3*2/fact(4)-(cos(32)*pi/4+power(5,3)+sqr(45)"

    It works in both degrees and radians for cosine, tangent, etc.

    http://sourceforge.net/projects/imathparser

    As you can see by the URL, the project is open source. Send your complaints, bugs, & comments (including praises! ) directly in the SourceForge web site.

    Regards,
    Ivan V.

    Hi,

    I am new to .NET and am having difficulty testing your math parser. Can you add a simple form that will load when you run the project?

    Thanks,

    mangel

    i think i have found the vb6 version for myself
    http://freesourcecode.net/vbprojects...n-Visual-Basic
    and this one is another good option
    http://www.Planet-Source-Code.com/vb...48568&lngWId=1

    but they are even worse than msscript.control in terms of efficiency
