I think you are over-complicating this, AND ignoring what the IEEE-754 
standard says about this.

That's not what the standard says. The standard says NAN as a limit 
should be treated as "no limit".

That will still apply. You can also pass 1.7976931348623157E+308, the 
largest possible float. (If we're talking about float arguments -- for 
int and Decimal, you can easily exceed that.)
