Constructors

Floor(Expression, Nullable<Double>)

Initializes a new instance of the Floor class.

Declaration
public Floor(Expression expression, double? bigM = default(double? ))
Parameters
Type Name Description
Expression expression

An expression of which the 'Floor' should be used.
System.Nullable<System.Double> bigM

Large number, only used if the bounds of the variables of the expressions are non-finite. It should be chosen large enough, so that the solution space is not cut. But choosing this value too large, it can cause numerical errors.

Properties

IsLinear

Gets a value indicating whether this operator always preserves linearity when used with linear expressions. Linearity can be re-established when modelling through linear constraints with a new variable.

Declaration
public override bool IsLinear { get; }
Property Value
Type Description
System.Boolean

true if linearity is preserved otherwise, false.
Overrides

PreservesLinearity

Gets a value indicating whether this operator always preserves linearity when used with terms. Linearity can be re-established when modelling through constraints with new variables.

Declaration
public override bool PreservesLinearity { get; }
Property Value
Type Description
System.Boolean

true if linearity is preserved otherwise, false.
Overrides

RepresentingVariable

A variable that can later be set to the representing variable when a model transformation for removing Floor- expressions is applied.

Declaration
public Variable RepresentingVariable { get; set; }
Property Value
Type Description
Variable
