function Round(X: Real): Int64;
It is used to round decimal numbers to the nearest whole number. If the decimal part is greater than 0.5, it rounds up; if it is less than 0.5, it rounds down. If the given number is exactly halfway (0.5) between two numbers, the result is always the 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;
{
numberFloat = 15.50;
ShowMessage('Round('+FloatToStr(numberFloat)+') = '+FloatToStr(Round(numberFloat)));
}
Output:
Round(15,5) = 16
