Delphi進製轉換函式

二進位制轉換

function bintodec(value: string): integer;

var  str: string;
i: integer;
begin

result := 0;
for i := 1 to length(str) do
result := result * 2 + ord(str[i]) - 48;
end;
function mod_num(n1, n2: integer): integer; //取餘數
begin
result := n1 - n1 div n2 * n2
end;
function reverse(s: string): string; //取反串
var  i, num: integer;
st: string;
begin
num := length(s);
st := '';
for i := num downto 1 do
begin
st := st + s[i];
end;
result := st;
end;
function dectobin(value: integer): string; //十進位制轉化二進位制
var  st: string;
n: integer;
begin
st := '';
n := value;
while n >= 2 do
begin
st := st + inttostr(mod_num(n, 2));
n := n div 2;
end;
st := st + inttostr(n);
result := reverse(st);
end;
