Solve the following python programming problem given the following code:
@ internationalizeDocstring 
def calc(self, irc, msg, args, text) : 
    "<math expression>

        Returns the value of the evaluated <math expression>.  The syntax is
        Python syntax.
the type of arithmetic is floating point.  Floating
        point arithmetic is used in order to prevent a user from being able to
        crash to the bot with something like '10**10**10**10'.  One consequence
        is that large values such as '10**24' might not be exact.
