Sets header 'Proxy-Authorization' using the given account and password strings:

req.proxy_basic_auth('my_account', 'my_password')
req['Proxy-Authorization']
# => "Basic bXlfYWNjb3VudDpteV9wYXNzd29yZA=="

Add the –http-proxy option

Calls the given block with each integer value from self up to limit; returns self:

a = []
5.upto(10) {|i| a << i }              # => 5
a                                     # => [5, 6, 7, 8, 9, 10]
a = []
-5.upto(0) {|i| a << i }              # => -5
a                                     # => [-5, -4, -3, -2, -1, 0]
5.upto(4) {|i| fail 'Cannot happen' } # => 5

With no block given, returns an Enumerator.

Calls the given block with each integer value from self down to limit; returns self:

a = []
10.downto(5) {|i| a << i }              # => 10
a                                       # => [10, 9, 8, 7, 6, 5]
a = []
0.downto(-5) {|i| a << i }              # => 0
a                                       # => [0, -1, -2, -3, -4, -5]
4.downto(5) {|i| fail 'Cannot happen' } # => 4

With no block given, returns an Enumerator.

Returns self.

Returns 1.

Returns the Complex object created from the numerators of the real and imaginary parts of self, after converting each part to the lowest common denominator of the two:

c = Complex.rect(Rational(2, 3), Rational(3, 4)) # => ((2/3)+(3/4)*i)
c.numerator                                      # => (8+9i)

In this example, the lowest common denominator of the two parts is 12; the two converted parts may be thought of as Rational(8, 12) and Rational(9, 12), whose numerators, respectively, are 8 and 9; so the returned value of c.numerator is Complex.rect(8, 9).

Related: Complex#denominator.

Returns the denominator of self, which is the least common multiple of self.real.denominator and self.imag.denominator:

Complex.rect(Rational(1, 2), Rational(2, 3)).denominator # => 6

Note that n.denominator of a non-rational numeric is 1.

Related: Complex#numerator.

Returns the numerator.

Returns the denominator (always positive).

With a block given, calls the block with each String value returned by successive calls to String#succ; the first value is self, the next is self.succ, and so on; the sequence terminates when value other_string is reached; returns self:

'a8'.upto('b6') {|s| print s, ' ' } # => "a8"

Output:

a8 a9 b0 b1 b2 b3 b4 b5 b6

If argument exclusive is given as a truthy object, the last value is omitted:

'a8'.upto('b6', true) {|s| print s, ' ' } # => "a8"

Output:

a8 a9 b0 b1 b2 b3 b4 b5

If other_string would not be reached, does not call the block:

'25'.upto('5') {|s| fail s }
'aa'.upto('a') {|s| fail s }

With no block given, returns a new Enumerator:

'a8'.upto('b6') # => #<Enumerator: "a8":upto("b6")>

Returns the numerator. The result is machine dependent.

n = 0.3.numerator    #=> 5404319552844595
d = 0.3.denominator  #=> 18014398509481984
n.fdiv(d)            #=> 0.3

Returns the denominator (always positive). The result is machine dependent.
