  • base_convert — Convert a number between arbitrary bases

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

    PHP Code:
    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).

          Code:
          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...

              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.
