Large Numbers into Strings

[SirP]

How would I turn a very large number into an identical string? The following happens with any number longer than fourteen digits.

] lua_run print( 999999999999999 )
> print( 999999999999999 )...
1e+015

[lua]print(string.format("%f",num))[/lua]
Perhaps?

This seems to work. Thank you very much.
