IMath.RoundUp

Fore Syntax

RoundUp(Value: Double; Precision: Integer): Double;

Fore.NET Syntax

RoundUp(Value: double; Precision: integer): double;

Parameters

Value. Rounded real number.

Precision. The number of decimal places, to which a number must be rounded.

Description

The RoundUp method returns the number, rounded to the nearest value, greater by module.

Comments

Values of input parameters cannot be empty.

If the number of decimal places is greater than 0, the number is rounded up to the specified number of decimal places after the decimal separator.

If the number of decimal places is equal to 0, the number is rounded to the nearest integer.

If the number of decimal places is less than 0, the number is rounded up, taking into account the decimal places before the decimal separator.

The RoundUp method is similar to the IMath.Round method, except that the number is always rounded down.

Fore Example

To execute the example, add a link to the MathFin system assembly.

Sub UserProc;
Var
    r1, r2, r3, r4: Double;
Begin
    r1 := Math.RoundUp(2.154956124,1);
    Debug.WriteLine(r1);
    r2 := Math.RoundUp(-50.654,-2);
    Debug.WriteLine(r2);
    r3 := Math.RoundUp(21.5,-1);
    Debug.WriteLine(r3);
    r4 := Math.RoundUp(-1.475,2);
    Debug.WriteLine(r4);
End Sub UserProc;

After executing the example the console window displays rounding results:

A number and the number of decimal places are positive: 2.2.
A number and the number of decimal places are negative: -100.
A number is positive and the number of decimal places is negative: 30.
A number is negative and the number of decimal places is positive: -1.48.

Fore.NET Example

The requirements and result of the Fore.NET example execution match with those in the Fore example.

Imports Prognoz.Platform.Interop.MathFin;
…
Public Shared Sub Main(Params: StartParams);
Var
    r1, r2, r3, r4: double;
    Math: MathClass = New MathClass();
Begin
    r1 := Math.RoundUp(2.154956124,1);
    System.Diagnostics.Debug.WriteLine(r1);
    r2 := Math.RoundUp(-50.654,-2);
    System.Diagnostics.Debug.WriteLine(r2);
    r3 := Math.RoundUp(21.5,-1);
    System.Diagnostics.Debug.WriteLine(r3);
    r4 := Math.RoundUp(-1.475,2);
    System.Diagnostics.Debug.WriteLine(r4);
End Sub;
