Simple forumula parser.

[nekrecart]

Hello,

I'm looking for a simple formula parser. The idea is that I store 3000 formula's as a string in a DB.
ex.
-6.055+0.0678*X-0.0147*Y

I'm looking for a free 'parser' that can calculate this. Only the basic operators (/,*,-,+,^) need to be supported.

Thanks,
N

I don't think it would be enough for you. It doesn't support variables, but at least you can build upon it.

In case you want to add variables support, this one supports six variables, but is in vb. You can use it as a reference.
