Convert Numbers To Hebrew (Views: 102)


Problem/Question/Abstract:

How can i change my 12345 numbers to hebrew numbering style ?

Answer:

Well I have created long ago in the pascal days a function to do this. A few month ago i converted it to Delphi, and created a new function to do it. It's much faster then the old one... but still it is to slow (I hope you can help me to make it even faster).

Note: this is a recorsive function, and also this is the first time i published it, I took it from my String unit, so it might be that there are some functions that apper only in this unit, so I'm sorry from a head :) :

const
  hZerrowToNine: array[0..9] of char =
  //  0   1   2   3   4   5   6   7   8   9
  (#255, '?', '?', '?', '?', '', '', '', '?', '?');
  //No Zerro in hebrew !!!!

  hTenToNinte: array[1..9] of char =
  // 10  20  30  40  50  60  70  80  90
  ('', '?', '?', '?', '?', '?', '?', '?', '');

  hHandredToFour: array[1..4] of char =
  //100 200 300 400
  ('', '', '?', '?');

    '2'..'9': result := hTenToNinteNumbers[strToInt(strNum[1])];

    result := #255;
