The 'calc' library contains the 'add2' function that takes 2 values and adds
|
|
them together. If either value is a string (or both of them are) 'add2' ensures
|
|
they are both strings, thereby resulting in a concatenated result.
|
|
NOTE: If a value submitted to the 'add2' function is a float, it must be done so
|
|
in quotes (i.e. as a string).
