Issue #17318 has been updated by Dan0042 (Daniel DeLorme).
Also see #16677 w/r edge cases.
-0.4**0.9 #=> -0.4383832905540869
-0.4.to_f**0.9 #=> (-0.416927285116376+0.13546788683122327i)
-(0.4).to_f**0.9 #=> -0.4383832905540869

Bug #17318: Raising float to the power of other issue
https://bugs.ruby-lang.org/issues/17318#change-88476
* Author: deXterbed (Manoj Mishra)
* Status: Rejected
* Priority: Normal
* ruby -v: 2.6.3
* Backport: 2.5: UNKNOWN, 2.6: UNKNOWN, 2.7: UNKNOWN
----------------------------------------
Raising a negative float to another float results in a complex number. Interestingly, doing the same thing without using variables works fine!
Sample Snippet:
$ irb
2.6.3 :001 > x=-0.4790529833050308
=> -0.4790529833050308
2.6.3 :002 > y=0.9918032786885246
=> 0.9918032786885246
2.6.3 :003 > x**y
=> (-0.48179173935576963+0.012409246172848264i)
2.6.3 :004 > -0.4790529833050308**0.9918032786885246
=> -0.4819515219418196
