BUG in Microsoft.JScript evaluator

I encountered with an interesting mis calculation (bug) on Microsoft.JScript expression evaluator.

It calculates the following expression:
"-180.188+38.1-19.05-(57.15)+142.088+19.05+57.15+76.2-19.05-(57.15)"

It returns "-7.105427357601E-15" instead of 0 (Zero)

To Evaluate an expression in a C# class, we need to add Microsoft.JScript and call Eval.JScriptEvaluate method:
using Microsoft.JScript;
...
public static string EvalJScript(string equation)
{
return Eval.JScriptEvaluate(equation, Vsa.VsaEngine.CreateEngine()).ToString();
}
