Ruby 2.3 ships with a new `Numeric#negative?` method. Rubinius implements this method since b92c84f, for internal usage though ; it delegates to the signbit C++ function. However, `signbit`'s behavior can't match MRI `Float#negative?`'s one since the former operates on the sign while the latter operates on the value (see http://git.io/vm1fg).

@robin850 if people are relying on checking a method for version, please direct them to https://github.com/brixen/redcard. We won't be fixing issues where people wrongly use methods or classes to infer the Ruby version. |

Hello,
Ruby 2.3 ships with a new
Numeric#negative?method. Rubinius implements this method since b92c84f, for internal usage though ; it delegates to thesignbitC++ function.However,
signbit's behavior can't match MRIFloat#negative?'s one since the former operates on the sign while the latter operates on the value (see here).This makes a test to fail on the Rails test suite (the same example is present in the
signbit's documentation and -0.0 is considered negative this time).Moreover, if people rely on feature detection rather than version checking, they may wrongly assume that the current running Ruby is 2.3+ checking if a float respond to
#negative?.Have a nice day!
