Round

function Round(const Number Extended):Int64;

The Round function rounds a floating point Number to an Integer value. The rounding uses Bankers rules, where an exact half value causes a rounding to an even number:

12.4 rounds to 12 12.5 rounds to 12 // Round down to even 12.6 rounds to 13

13.4 rounds to 13 13.5 rounds to 14 // Round up to even 13.6 rounds to 14

Example:

var
  numberFloat : Float;

begin

  numberFloat := 15.50;  
  ShowMessage('Round('+FloatToStr(numberFloat)+') = '+FloatToStr(Round(numberFloat)));

end;

Output:

Round(15,5) = 16
