All Implemented Interfaces:

Serializable, Cloneable

Enclosing class:

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