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
Parses a Range header value ranges_specifier
Parses a Range header value ranges_specifier
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.abs, cmp.arg].
Complex(1, 2).polar #=> [2.23606797749979, 1.1071487177940904]
Returns the numerator.
1 2 3+4i <- numerator
- + -i -> ----
2 3 6 <- denominator
c = Complex('1/2+2/3i') #=> ((1/2)+(2/3)*i)
n = c.numerator #=> (3+4i)
d = c.denominator #=> 6
n / d #=> ((1/2)+(2/3)*i)
Complex(Rational(n.real, d), Rational(n.imag, d))
#=> ((1/2)+(2/3)*i)
See denominator.
Returns the value as a rational if possible (the imaginary part should be exactly zero).
Complex(1.0/3, 0).rationalize #=> (1/3) Complex(1, 0.0).rationalize # RangeError Complex(1, 2).rationalize # RangeError
See to_r.
Returns zero as a rational. The optional argument eps is always ignored.
Returns zero.
Returns 0 if the value is positive, pi otherwise.
Returns an array; [num, 0].
Returns an array; [num.abs, num.arg].
Returns the numerator.
