Re: SE4 Templatizer Ready for Download!
Will it support all sorts of funky math? Exponents, sin, custom user defined functions, etc.?

Re: SE4 Templatizer Ready for Download!
I'm hoping to basically put in anything that's in the .NET math library, so exponents and sines should be in. As for user-defined functions, I wasn't planning for them, but if you want to add functions, the program is designed to be extensible so you can code them yourself if you know a .NET language such as C#  Basically, I have an Expression class with subclasses for all the different types of expressions there can be (unary operations, constants, functions, etc.) and to add a function you'd have to derive a class from one of my base classes and implement its Value property which does the actual computation.
If I ever get this working I'll post it on www.codeproject.com; my main problem is to get the input string parsed out into an expression tree... but I've read about converting to Reverse Polish Notation and that should prove helpful with everything except the functions... and the (non-user-defined) functions shouldn't be too much after that, it's just a matter of getting them to take multiple parameters...

Re: SE4 Templatizer Ready for Download!
User defined functions are necessary to prevent having to put the same formula code in 700 entries...  |

Re: SE4 Templatizer Ready for Download!
Hmm, that might be doable if I just had a separate functions.txt listing all the functions and what they evaluate to; they'd just be evaluated Last in the precedence order, I guess...

I wasn't trying to be funny, I want someone to explain the topic name.

Re: SE4 Templatizer Ready for Download!
Negating a number means turning 5 into -5, or -3 into 3, or whatever - basically subtracting it from zero.
