Returns an array of modules defined within the receiver.

module A
  refine Integer do
  end

  refine String do
  end
end

p A.refinements

produces:

[#<refinement:Integer@A>, #<refinement:String@A>]

Returns the list of Modules nested at the point of call.

module M1
  module M2
    $a = Module.nesting
  end
end
$a           #=> [M1::M2, M1]
$a[0].name   #=> "M1::M2"

Return the fractional part of the number, as a BigDecimal.

Returns the exponent of the BigDecimal number, as an Integer.

If the number can be represented as 0.xxxxxx*10**n where xxxxxx is a string of digits with no leading zeros, then n is the exponent.

Returns the numerator.

Rational(7).numerator        #=> 7
Rational(7, 1).numerator     #=> 7
Rational(9, -4).numerator    #=> -9
Rational(-2, -10).numerator  #=> 1

Returns true if rat is less than 0.

Returns a simpler approximation of the value if the optional argument eps is given (rat-|eps| <= result <= rat+|eps|), self otherwise.

r = Rational(5033165, 16777216)
r.rationalize                    #=> (5033165/16777216)
r.rationalize(Rational('0.01'))  #=> (3/10)
r.rationalize(Rational('0.1'))   #=> (1/3)

Parse an HTTP query string into a hash of key=>value pairs.

params = CGI.parse("query_string")
  # {"name1" => ["value1", "value2", ...],
  #  "name2" => ["value1", "value2", ...], ... }

Returns a new Date object constructed from the present date:

Date.today.to_s # => "2022-07-06"

See argument start.

Note: This method recognizes many forms in string, but it is not a validator. For formats, see “Specialized Format Strings” in Formats for Dates and Times

If string does not specify a valid date, the result is unpredictable; consider using Date._strptime instead.

Returns a hash of values parsed from string:

Date._parse('2001-02-03') # => {:year=>2001, :mon=>2, :mday=>3}

If comp is true and the given year is in the range (0..99), the current century is supplied; otherwise, the year is taken as given:

Date._parse('01-02-03', true)  # => {:year=>2001, :mon=>2, :mday=>3}
Date._parse('01-02-03', false) # => {:year=>1, :mon=>2, :mday=>3}

See argument limit.
