base_convert — Convert a number between arbitrary bases

[kingzooly]

i am converting a php script to lua but having problems with base_convert — Convert a number between arbitrary bases

string base_convert ( string $number , int $frombase , int $tobase ) 

what would be the lua version.

After a quick search I found this, the script might work as a starting point.

I will give this a look over, the problem with others I see do far will only take 2 values not 3 but from what I read of the funtion it was no auto detecting what the base it was given so I was not sure how to use them as they was no documents for them, I give this a look thanks.

Is there a function that mimics the php split functions I have one that someone created but does not work in AMS and then one that says it needs string but php split takes table and string.

split is deprecated in PHP and should not be used any more, use explode($pattern, $str).

function explode(div,str) -- credit: http://richard.warburton.it
  if (div=='') then return false end
  local pos,arr = 0,{}
  -- for each divider found
  for st,sp in function() return string.find(str,div,pos,true) end do
    table.insert(arr,string.sub(str,pos,st-1)) -- Attach chars left of current divider
    pos = sp + 1 -- Jump past current divider
  end
  table.insert(arr,string.sub(str,pos)) -- Attach chars right of last divider
  return arr
end

I used to have a base conversion function in Lua somewhere, but I can't seem to find it right now...

I am converting a script to work in AMS, but if that gives the same result I happly us it

explode does the same as split, it will slice a string into pieces based on a specified delimiter. :yes

As for base_convert, between which bases do you need to be able to convert?

32 to 10 so far its used a few times so not sure converting it bit by bit at the moment
and I am sure there is back to 10 from 32 at some point.

I still have an old base conversion class in PHP which I will try to translate to Lua. It will be improvisation, however it should do the trick for like every possible base.

One note though, the base.convert I will write will be case sensitive. 4az9 ~= 4Az9.

There ya go, test this well!
