Hardy Ferentschik commented on BVAL-192:
----------------------------------------

@Emmanuel, do you think this feature is worth adding Hibernate Validator specific versions of these constraints for now? I tend to say no. WDYT?

> Hi, may I suggest to enhance {{@DecimalMin}}/{{@DecimalMax}} constraints with additional _exclusive_ boolean attribute? This would allow to define a constraints like:
> {code}
> // a positive non-zero decimal number
> @DecimalMin(value = "0.0", exclusive = true)
> {code}
> {code}
> // a negative non-zero decimal number
> @DecimalMax(value = "0.0", exclusive = true)
> {code}
> This makes sense when dealing with decimal numbers where one might want to allow a number regardless of the precision.
> {{@DecimalMin("0.0001")}} vs. {{@DecimalMin("0.000000001")}}, etc.
> To maintain backward compatibility, default value for new _exclusive_ boolean attribute should be {{false}}
