IMath.Floor

Fore Syntax

Floor(Value: Double; Precision: Double): Double;

Fore.NET Syntax

Floor(Value: double; Precision: double): double;

Parameters

Value. Rounded real number.

Precision. The multiple, up to which the value must be rounded.

Description

The Floor method rounds down the number to the nearest number, which is a multiple of precision.

Comments

Parameter values cannot be empty.

If the number and precision are positive, the value is rounded down, if the number and precision are negative, the value is rounded up. If a number is negative and precision is positive, the value is rounded down.

Fore Example

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

Sub UserProc;
Var
    r1, r2, r3: Double;
Begin
    r1 := Math.Floor(3.7,2);
    Debug.WriteLine(r1);
    r2 := Math.Floor(-2.5,-2);
    Debug.WriteLine(r2);
    r3 := Math.Floor(-2.5,2);
    Debug.WriteLine(r3);
End Sub UserProc;

After executing the example the console window displays rounding results:

Number and precision are positive: 2.
Number and precision are negative: -2.
Number is negative and precision is positive: -4.

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: double;
    Math: MathClass = New MathClass();
Begin
    r1 := Math.Floor(3.7,2);
    System.Diagnostics.Debug.WriteLine(r1);
    r2 := Math.Floor(-2.5,-2);
    System.Diagnostics.Debug.WriteLine(r2);
    r3 := Math.Floor(-2.5,2);
    System.Diagnostics.Debug.WriteLine(r3);
End Sub;
