Round2Up
Similar to Round2, the function Round2Up performs biased rounding and returns aValue rounded to the number of decimal places specified by aDigit.
However, this function rounds 1-4 down, and 5-9 is always rounded up.
Where aDigit is 0, the function applies the same rules but just returns the integer –
Round2Up(4.2,0) is 4.
Round2Up(4.5,0) is 5.
Round2Up(4.8,0) is 5.
Unique to Statelake, Round2Up is the most commonly used rounding function.
Also refer to Round, Round2, and RoundBR.
Declaration: Function Round2Up( aValue : Extended; aDigit : integer) : Extended
Examples follow.
Procedure OnMapEvent(var Value:variant);begin Value := Round2Up(123.454,2); // result is 123.45 Value := Round2Up(123.455,2); // result is 123.46 Value := Round2Up(123.465,2); // result is 123.47 Value := Round2Up(123.4558,3); // result is 123.456 Value := Round2Up(123.4553,3); // result is 123.455 Value := Round2Up(745.554,2); // result is 745.55 Value := Round2Up(745.555,2); // result is 745.56 Value := Round2Up(80.374,2); // result is 80.37 Value := Round2Up(80.4566,3); // result is 80.46 Value := Round2Up(80.5553,3); // result is 80.56 end;
