Constructs proper parameters from arguments

Return an array of extra arguments for the command. The extra arguments come from the gem configuration file read at program startup.

Adds extra args from ~/.gemrc

Validates the Diffie-Hellman parameters associated with this instance. It checks whether a safe prime and a suitable generator are used. If this is not the case, false is returned.

Sets saner defaults optimized for the use with HTTP-like protocols.

If a Hash params is given, the parameters are overridden with it. The keys in params must be assignment methods on SSLContext.

If the verify_mode is not VERIFY_NONE and ca_file, ca_path and cert_store are not set then the system default certificate store is used.

Prints obj on the given port (default $>). Equivalent to:

def display(port=$>)
  port.write self
  nil
end

For example:

1.display
"cat".display
[ 4, 5, 6 ].display
puts

produces:

1cat[4, 5, 6]

Returns self.

Returns the value as a rational. The optional argument eps is always ignored.

Returns a complex object which denotes the given rectangular form.

Complex.rectangular(1, 2)  #=> (1+2i)

Returns a complex object which denotes the given polar form.

Complex.polar(3, 0)            #=> (3.0+0.0i)
Complex.polar(3, Math::PI/2)   #=> (1.836909530733566e-16+3.0i)
Complex.polar(3, Math::PI)     #=> (-3.0+3.673819061467132e-16i)
Complex.polar(3, -Math::PI/2)  #=> (1.836909530733566e-16-3.0i)

Returns the imaginary part.

Complex(7).imaginary      #=> 0
Complex(9, -4).imaginary  #=> -4

Returns the angle part of its polar form.

Complex.polar(3, Math::PI/2).arg  #=> 1.5707963267948966

Returns an array; [cmp.real, cmp.imag].

Complex(1, 2).rectangular  #=> [1, 2]

Returns an array; [cmp.abs, cmp.arg].

Complex(1, 2).polar  #=> [2.23606797749979, 1.1071487177940904]
