IModelling.Remainder

Syntax

Remainder(Input1: Variant; Input2: Variant): Variant;

Parameters

Input1. Variable.

Input2. Divisor.

Description

The Remainder method returns remainder of division of variable points values by a specified number.

Example

Executing the example requires that the repository contains a modeling container with the MS identifier. This container includes a model with the MODEL_D identifier that is calculated by the determinate equation method and contains more than one input variable.

Add links to the Metabase and Ms system assemblies.

    // Get repository
    Mb := MetabaseClass.Active;
    // Get modeling container
    ModelSpace := Mb.ItemById("MS").Bind;
    // Get model
    ModelObj := Mb.ItemByIdNamespace("MODEL_D", ModelSpace.Key).Edit;
    Model := ModelObj As IMsModel;
    // Get model calculation parameters
    Transf := Model.Transform;

    Determ := Formula.Method As IMsDeterministicTransform;
    // Get the first input variable
    TransVar := Transf.Inputs.Item(0);
    Slice := TransVar.Slices.Item(0);
    TermInfo := Transf.CreateTermInfo;
    TermInfo.Slice := Slice;
    // Set mode of passing variable into calculation
    TermInfo.Type := MsFormulaTermType.Pointwise;
    // Remember model calculation settings for points of the first input variable
    Inp_1 := TermInfo.TermInnerText;
    // Get the second input variable
    TransVar := Transf.Inputs.Item(1);
    Slice := TransVar.Slices.Item(0);
    TermInfo := Transf.CreateTermInfo;
    TermInfo.Slice := Slice;
    // Set mode of passing variable into calculation
    TermInfo.Type := MsFormulaTermType.Pointwise;
    // Remember model calculation settings for points of the second input variable
    Inp_2 := TermInfo.TermInnerText;
    // Get model calculation expression
    Expr := Determ.Expression;
    Expr.References := "Ms";
    // Set model calculation expression
    Expr.AsString := "Remainder(" + Inp_1 + ", " + Inp_2 + ")";
    // Check if the expression is correct
    If Expr.Valid
        // If the expression is set correctly, save the model
        Then ModelObj.Save;
        // If expression is not correct, output message to console window
        Else Debug.WriteLine("Model is not saved: error in the formula");
    End If;
End Sub UserProc;

After executing the example the model will return remainder of division of the first input variable points by the corresponding points of the second input variable.

Example of Use in Expressions

Expression 1:

Remainder({Brazil|BCA},{China|BCA})

Result: the remainder of the division of Brazil|BCA factor observations is calculated to the corresponding China|BCA factor observations.

Use: it can be used in formulas of cross functional expression editor in any platform tool where it is available.

Expression 2:

Remainder(X1,3)

Result: the remainder of X1 factor points division to three is calculated.

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

Expression 3:

Remainder(7,3)

Result: 0.33.

Application: it can be used in any expressions.
