What about this:

math.isfloat(1)
-> false
math.isfloat(1.0)
-> true

I played around with this a bit.  The only thing I found that appears to 
be missing is the ability to determine the actual type of the number.  
That is:

    a = 5
    ttype(a) == 'number'

    b = 5.0
    ttype(b) == 'number

It would be nice if there was a method to do so in Lua itself.  One use 
case is for serializing integer values to disk in text form properly.

Thanks!
