[DUG] integer or int64

[John Bird]

Quite a few built in Delphi functions accept either integer or int64 as an 
argument, I checked into inttostr for instance, in that case its asm code.

I have quite a few standard number processing routines, and up to now have 
done one version for integer, and another for int64.

Is it feasible to have an argument/parameter to a function that can be 
either (like Delphi does)?

is it possible to test whether such an argument is either integer or int64?

Related - Does anyone know if an int128 is on the cards down the track?  (I 
have some functions that use numbers nearly up to int64 limit - 17 of the 18 
digits decimal length)
