        EqualZero

All Implemented Interfaces:

Serializable, Cloneable

Enclosing class:

EltRangeFloat
```
public static class EltRangeFloat.EqualZero
extends EltRangeFloat
```
Internal invariant representing double scalars that are equal to zero. Used for non-instantiating suppressions. Will never print since OneOf accomplishes the same thing.
