What's more, 1.311500322e+12 is a valid representation of a date/time,
according to a ridiculously broken game server I've worked with.
That's the number of milliseconds since 1970, stored as floating
point. I'm sure this makes sense to somebody...

Not all possible representations are equally sane. I'm with Ben;
'165.00' is not a string representation of an integer - but you CAN
take that string, validate it as representing a number that can be
represented as an integer, and evaluate what integer it is.
