I am working on math engine in C# for my teacher, and I don't know how to parse something like this string needToBeCalculated = "1/2 + (2 + 3 /2 * (3+1))";, To an int or long. I know thatlong Calculated = long.Parse(needToBeCalculated ); this doesn't work. But is there a build in method or some kind of a design pattern that i must use ?

2Simple: `double result = (double)new DataTable().Compute("1/2 + (2 + 3 /2 * (3+1))", null)` ;-) – Tim Schmelter Jul 01 '15 at 10:46

You can take a look at [this](http://stackoverflow.com/a/392355/1677264) and [this](http://stackoverflow.com/a/4620486/1677264). – Cheshire Cat Jul 01 '15 at 10:54

@denislavlicov: exponentiation is not supported by `Compute`, look at [the remarks section of `DataColumn.Expression`](https://msdn.microsoft.com/en-us/library/system.data.datacolumn.expression(v=vs.90).aspx) to see what is supported. – Tim Schmelter Jul 01 '15 at 10:58
