Subject: [ruby-core:105388] [Ruby master Bug#18188] -1 ** 0 is 1 not -1

Issue #18188 has been updated by jeremyevans0 (Jeremy Evans).

Status changed from Open to Rejected

`-1**0` is parsed as `-(1**0)`, not `(-1)**0`. `(-1)**0` returns `1`

----------------------------------------
Bug #18188: -1 ** 0 is 1 not -1
https://bugs.ruby-lang.org/issues/18188#change-93801

* Author: r.burrowes@auckland.ac.nz (Robert Burrowes)
* Status: Rejected
* Priority: Normal
* ruby -v: ruby 3.0.2p107 (2021-07-07 revision 0db68f0233) [x86_64-freebsd11.2]
* Backport: 2.6: UNKNOWN, 2.7: UNKNOWN, 3.0: UNKNOWN
----------------------------------------
Any negative number to the power of 0 is 1, but ruby is returning -1.

i.e. it should be   n == 0 ? 1 : x ** n

/usr/local/ruby3.0/bin/ruby
puts -1**0
-1
