Delphi equivalent of utoa from C
Is there a Delphi equivalent of the C utoa function, that allows me to provide a radix? I'm using Delphi 2007开发者_Python百科, and have to read a file which has been named using a radix of 32 with utoa. I'd rather not re-invent the wheel and introduce my own bugs. [Edit:] It would operate the same way that IntToStr operates, which uses base 10 so the equivalent utoa of IntToStr would be utoa(value, 10);
As an example, the integer 100 should return a value of "34".
Hmm, I did a search of my old code, and found this, which appears to work!
function ItoA(value : Cardinal; Radix : Cardinal) : string;
const
acCharRef : array [0 .. 35] of char
= (
'0', '1', '2', '3', '4', '5', '6', '7',
'8', '9', 'A', 'B', 'C', 'D', 'E', 'F',
'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N',
'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V',
'W', 'X', 'Y', 'Z'
);
var
nIndex : Integer;
szBuild : string;
begin
{* Now loop, taking each digit as modulo radix, and reducing the value
* by dividing by radix, until the value is zeroed. Note that
* at least one loop occurs even if the value begins as 0,
* since we want "0" to be generated rather than "".
*}
szBuild := '';
repeat
nIndex := value mod radix;
szBuild := acCharRef[nIndex] + szBuild;
value := value div radix;
until value = 0;
result := szBuild;
end;
