Hey Mark.
Don't complain because *you* are easily able to work around your
"not-reading-the-dictionary" ;-))
From the baseconvert entry of the dictionary:
baseConvert(number, originalBase, destinationBase)
The number must be an integer between zero and 4,294,967,295 (2^32 -
1).
The engine hasn't ever done range checks on integers - mainly because
numbers are doubles so (in most ases) you just lose accuracy / precision
as the numbers get larger. In this case it *could* because it is
actually using integers.
Although, perhaps, baseConvert should be a purely string->string
operation - I think that can be done relatively easily without ever
having to convert to an integer. This would mean you would be able to
base-convert any sized number, although you wouldn't necessarily be able
to perform non-precision losing arithmetic operations on the result.
Warmest Regards,
Mark.
