public class EqualRounded
extends AbstractExpression

The equalRounded operator takes two sub-expressions which must both have single cardinality and have A numerical base-type. The result is A single boolean with A value of true if the two expressions are numerically equal after rounding and false if they are not. If either sub-expression is NULL then the operator results in NULL.

public void setFigures(java.lang.Integer figures)

Sets new value of figures attribute.

Parameters:

figures - new value of figures attribute

See Also:

getFigures()

validateAttributes

protected ValidationResult validateAttributes()

Description copied from class: AbstractNode

Validates attributes of this node.

Overrides:

validateAttributes in class AbstractNode
