The current code base is not uniform. After some discussion,
we have chosen to go with double quotes by default.

- Instead of using `to_f.phase`, just use `to_f.negative`?.
- This change works same for all cases except when number is "-0.0".
-0.0.to_f.negative? => false
-0.0.to_f.phase? => pi
- So -0.0 will be treated as positive from now onwards.
- So this change reverts changes from https://github.com/rails/rails/pull/6512.
- But it should be acceptable as we could not find any currency which
supports negative zeros.

https://github.com/ruby/ruby/pull/579 - there is a new optimization
since ruby 2.2
Previously regexp patterns were faster (since a string was converted to
regexp underneath anyway). But now string patterns are faster and
better reflect the purpose.
Benchmark.ips do |bm|
bm.report('regexp') { 'this is ::a random string'.gsub(/::/, '/') }
bm.report('string') { 'this is ::a random string'.gsub('::', '/') }
bm.compare!
end
# string: 753724.4 i/s
# regexp: 501443.1 i/s - 1.50x slower
