Hi all

In my application where in i have a string saying value = "2+3-4" . Is there any way given this string , i need the mathematical evaluation of the string inside i.e it should give me 1.

I feel the implementation for this will not be that easy , but is there any third party API which has this facility . Else can any one let me know how to go about this . The expression might include * and %

Let me know if there are any options
