Returns the numerator.
Rational(7).numerator #=> 7 Rational(7, 1).numerator #=> 7 Rational(9, -4).numerator #=> -9 Rational(-2, -10).numerator #=> 1
Returns the denominator (always positive).
Rational(7).denominator #=> 1 Rational(7, 1).denominator #=> 1 Rational(9, -4).denominator #=> 4 Rational(-2, -10).denominator #=> 5 rat.numerator.gcd(rat.denominator) #=> 1
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)
Set the scan pointer to the end of the string and clear matching data.
returns array of WIN32OLE_PARAM object corresponding with method parameters.
tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'Workbook')
method = WIN32OLE_METHOD.new(tobj, 'SaveAs')
p method.params # => [Filename, FileFormat, Password, WriteResPassword,
ReadOnlyRecommended, CreateBackup, AccessMode,
ConflictResolution, AddToMru, TextCodepage,
TextVisualLayout]
Returns the methods available to this delegate object as the union of this object’s and _getobj_ methods.
Explicitly terminate option processing.
Returns true if option processing has terminated, false otherwise.
Returns a new ipaddr built by converting the IPv6 address into a native IPv4 address. If the IP address is not an IPv4-mapped or IPv4-compatible IPv6 address, returns self.
Returns true if this is an orthogonal matrix Raises an error if matrix is not square.
Terminates option parsing. Optional parameter arg is a string pushed back to be the first non-option argument.
Add separator in summary.
