What is your suggestion? To dispense with `-0.0`?

----------------------------------------
Bug #17098: Float#negative? reports negative zero as not negative
https://bugs.ruby-lang.org/issues/17098#change-86886

* Author: chrisseaton (Chris Seaton)
* Status: Open
* Priority: Normal
* Backport: 2.5: UNKNOWN, 2.6: UNKNOWN, 2.7: UNKNOWN
----------------------------------------
Is this intended behaviour?

```
irb(main):001:0> neg_zero = -0.0
=> -0.0
irb(main):002:0> neg_zero.negative?
=> false
irb(main):003:0> neg_zero < 0
=> false
```

It happens because `Numeric#negative?` uses `< 0`. My understanding of IEEE floating point is that negative zero is not less than zero, but I think it should still report as negative.
