IntToStr

function IntToStr(Number Integer):string;
function IntToStr (BigNumber Int64:string;

The IntToStr function converts an Integer Number or Int64 BigNumber into a string. It has two forms : the latter supporting very large integers. It is normally used for display purposes.

Example:

var
  NormalInteger : Integer;
  BigInteger    : Int64;
begin
  NormalInteger := 1234656789;          // Largest possible Integer value
  BigInteger    := 1234656789123465681; // Largest possible Int64 value

  ShowMessage('NormalInteger :     '+IntToStr(NormalInteger));
  ShowMessage('BigInteger :        '+IntToStr(BigInteger));
  ShowMessage('Calculated number : '+IntToStr(27 * 4));
end;

Output:

NormalInteger :     1234656789
BigInteger :        1234656789123465681
Calculated number : 108
