[REBOL] Re: 32 bit - dword values

Hi Elan,
We were at the time looking for a solution to convert dword values to an
ip address for the IRCBOT we were creating. Kinners came up with the
following solution:
dec2tuple: func [long] [
to-tuple reduce [
to-integer long / 16777216
to-integer long / 65536 // 256
to-integer long / 256 // 256
to-integer long // 256
]
]
This function is so useful I thought RT should put this into /Core. How
many people could use this? answer: alot! Thanks for your feedback.

that special precautions must be taken to prevent math overflow errors. Can
someone from RT tell us how we should handle these issues. For example if I
do a to-hex 5555555555 I get an error:
