If it happens compilator will throw the exception converting error which you can handle using structure try { ...//your code } catch (Exception) { ... //your code in the case of the exception }

Answer 2

There's a number of ways you can do it.

variable = variable * 1 multiplies the variable by one, and converts the variable to a number if it's a string. Because * 1 doesn't change the value, this is one way of converting a string into an integer.
