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
