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

Zero has one digit, but Math.log10(0) returns -Infinity. The method
needs to special-case zero.
The patch adds a regression test that is not clearly related to the
underlying issue because digit_count is private and has no coverage.
Gray area.

:precision was incorrectly being applied to Rationals
before:
ActiveSupport::NumberHelper.number_to_rounded Rational(10, 3), precision: 2
=> "3.3"
after:
ActiveSupport::NumberHelper.number_to_rounded Rational(10, 3), precision: 2
=> "3.33"

`ActiveSupport::SafeBuffer` values aren't mangled.

Closes #14405.
This is a follow-up to 9e997e9039435617b6a844158f5437e97f6bc107 to restore
the documented behavior.

This reads a lot better, and we won't need to try start_with? for blank
delimiters.
Also rename method name to read better.

The conversion without area code already changed the passed number in
place, so change the other method to do the same.

Refactor and clean up number helpers
Conflicts:
activesupport/lib/active_support/number_helper.rb

Due to the overall complexity of each method individually as well as the
global shared private module methods, this pulls each helper into it's
own converter class inheriting from a generic `NumberBuilder` class.
* The `NumberBuilder` class contains the private methods needed for each helper
method an eliminates the need for special definition of specialized private
module methods.
* The `ActiveSupport::NumberHelper::DEFAULTS` constant has been moved
into the `NumberBuilder` class because the `NumberBuilder` is the only
class which needs access to it.
* For each of the builders, the `#convert` method is broken down to
smaller parts and extracted into private methods for clarity of purpose.
* Most of the mutation that once was necessary has now been eliminated.
* Several of the mathematical operations for percentage, delimited, and
rounded have been moved into private methods to ease readability and
clarity.
* Internationalization is still a bit crufty, and definitely could be
improved, but it is functional and a bit easier to follow.
The following helpers were extracted into their respective classes.
* `#number_to_percentage` -> `NumberToPercentageConverter`
* `#number_to_delimited` -> `NumberToDelimitedConverter`
* `#number_to_phone` -> `NumberToPhoneConverter`
* `#number_to_currency` -> `NumberToCurrencyConverter`
* `#number_to_rounded` -> `NumberToRoundedConverter`
* `#number_to_human_size` -> `NumberToHumanSizeConverter`
* `#number_to_human` -> `NumberToHumanConverter`
