org.codehaus.groovy.grails.validation.ScaleConstraint
- All Implemented Interfaces:
- Constraint
class ScaleConstraint
- extends AbstractConstraint
A constraint to manage the scale for floating point numbers (i.e., the
number of digits to the right of the decimal point).
This constraint supports properties of the following types:
- java.lang.Float
- java.lang.Double
- java.math.BigDecimal (and its subclasses)
When applied, this constraint 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.
