You would in most cases have a value of some sort, but you can't always 
relay on that it will for ever be like that (we know PHP makes some big 
changes from time to time) and what happens further down if you have 
negative values or huge values.

Validate what you get and make a sanity check on what you got before you 
calculate the realtime value.

There are quite many is_* functions, among those you have 
is_numeric()[1] and another one is isset()[2] which gives you true or false.
