IModelling.Int

Fore Syntax

Int(Input: Variant): Variant;

Fore.NET Syntax

Int(Input: object; Context: Prognoz.Platform.Interop.Fore.ForeRuntime.Context): object;

Parameters

Input. Variable.

Description

The Int method rounds values of selected variable down to the nearest integer.

Comments

Range of input variable available values: [MinInteger; MaxInteger]. MinInteger = -231, MaxInteger = 231 - 1.

If input parameter goes beyond the left border of available values, the method returns MinInteger.

If input parameter goes beyond the right border of available values, the method returns MaxInteger.

Fore Example

Executing the example requires that the repository contains a modeling container with the MS identifier. A model with the MODEL_D identifier calculated by the method of determinate equation and containing at least one input variable must be available in this container.

Add links to the Metabase, Ms system assemblies.

Sub UserProc;
Var
    Mb: IMetabase;
    ModelSpace, ModelObj: IMetabaseObject;
    Transf: IMsFormulaTransform;
    Formula: IMsFormula;
    Model: IMsModel;
    Determ: IMsDeterministicTransform;
    TransVar: IMsFormulaTransformVariable;
    Slice: IMsFormulaTransformSlice;
    TermInfo: IMsFormulaTermInfo;
    Expr: IExpression;
Begin
    Mb := MetabaseClass.Active;
    ModelSpace := Mb.ItemById("MS").Bind;
    ModelObj := Mb.ItemByIdNamespace("MODEL_D", ModelSpace.Key).Edit;
    Model := ModelObj As IMsModel;
    Transf := Model.Transform;
    Formula := Transf.FormulaItem(0);
    Determ := Formula.Method As IMsDeterministicTransform;
    TransVar := Transf.Inputs.Item(0);
    Slice := TransVar.Slices.Item(0);
    TermInfo := Transf.CreateTermInfo;
    TermInfo.Slice := Slice;
    Expr := Determ.Expression;
    Expr.References := "Ms";
    Expr.AsString := "Int(" + TermInfo.TermInnerText + ")";
    If Expr.Valid Then ModelObj.Save;
        Else Debug.WriteLine(Model is not saved: error in formula);
    End If;
End Sub UserProc;

After executing the example the model rounds values of the first input variable points to the nearest integer.

Fore.NET Example

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

Imports Prognoz.Platform.Interop.Ms;
Imports Prognoz.Platform.Interop.ForeSystem;
…
Public Shared Sub Main(Params: StartParams);
Var
    Mb: IMetabase;
    ModelSpace, ModelObj: IMetabaseObject;
    Transf: IMsFormulaTransform;
    Formula: IMsFormula;
    Model: IMsModel;
    Determ: IMsDeterministicTransform;
    TransVar: IMsFormulaTransformVariable;
    Slice: IMsFormulaTransformSlice;
    TermInfo: IMsFormulaTermInfo;
    Expr: IExpression;
Begin
    Mb := Params.Metabase;
    ModelSpace := Mb.ItemById["MS"].Bind();
    ModelObj := Mb.ItemByIdNamespace["MODEL_D", ModelSpace.Key].Edit();
    Model := ModelObj As IMsModel;
    Transf := Model.Transform;
    Formula := Transf.FormulaItem[0];
    Determ := Formula.Method As IMsDeterministicTransform;
    TransVar := Transf.Inputs.Item[0];
    Slice := TransVar.Slices.Item[0];
    TermInfo := Transf.CreateTermInfo();
    TermInfo.Slice := Slice;
    Expr := Determ.Expression;
    Expr.References := "Ms";
    Expr.AsString := "Int(" + TermInfo.TermInnerText + ")";
    If Expr.Valid Then ModelObj.Save();
        Else System.Diagnostics.Debug.WriteLine("Model is not saved: error in formulaquot;);
    End If;
End Sub;

Example of Use in Expressions

Expression 1:

Int({Brazil|BCA})

Result: Brazil|BCA factor observations are rounded down to the nearest integer.

Use: it can be used in formulas of calculated series of time series database and model formulas of modeling container that is a child of the time series database.

Expression 2:

Int(X1)

Result: X1 factor points are rounded down to the nearest integer.

Use: it can be used in model formulas of modeling container.

Expression 3:

Int(4.6)

Result: 4.

Use: it can be used in formulas of calculated series of time series database and modeling container models.
