org.codehaus.groovy.grails.validation
[Java] Class ScaleConstraint

java.lang.Object
  org.codehaus.groovy.grails.validation.AbstractConstraint
      org.codehaus.groovy.grails.validation.ScaleConstraint

public class ScaleConstraint
extends AbstractConstraint

Manages the scale for floating point numbers (i.e., the number of digits to the right of the decimal point). Supports properties of the following types:

When applied, determines if the number includes more nonzero decimal places than the scale permits. If so, it rounds the number to the maximum number of decimal places allowed by the scale. The rounding behavior described above occurs automatically when the constraint is applied. This constraint does not generate validation errors.
