Hex - Decimal converter

You never know when you might need one of these.

Any one for a spot of programming?

I don't know who the Unicode Consortium think they are serving by being difficult and
presenting everything in Hexadecimal (and on the left is all the work I had to do to hack
their document with Decimal numbers).

Just like Tarzan; now swings both ways:

Aha; now I realised I was missing something.

Hi Richmond,

thanks a lot for the inspiration. I was looking for a kind of function to do that in LC and developed a shorter one, inspired by your solution:

Cheers

Code: Select all

function Hex2Int tHex
   -- INPUT: hex value
   -- OUTPUT: integer

   put the length of tHex into tLength
   put -1 into tPower
   repeat with i = tLength down to 1
      
      add 1 to tPower
      put char i of tHex into tChar
      if tChar = "A" then put 10 into tChar
      if tChar = "B" then put 11 into tChar
      if tChar = "C" then put 12 into tChar
      if tChar = "D" then put 13 into tChar
      if tChar = "E" then put 14 into tChar
      if tChar = "F" then put 15 into tChar
      add tChar * (16^tPower) to tInt
      
   end repeat
   
   return tInt

end Hex2Int

That's super to know.

This may have already come up, but why write a base conversion routine when one is alreayd built into Livecode?

See baseConvert(number, originalBase, destinationBase) in the Dictionary

For base hex to decimal converstion:

put baseConvert(myHexNumberVariable,16,10) into myDecNumberVariable

I did it for fun.
