cmp - numeric â complex Instance Public methods Performs subtraction. Complex(2, 3) - Complex(2, 3) #=> (0+0i) Complex(900) - Complex(1) #=> (899+0i) Complex(-2, 9) - Complex(-9, 2) #=> (7+7i) Complex(9, 8) - 4 #=> (5+8i) Complex(20, 9) - 9.8 #=> (10.2+9i)

visit_Integer(o) Instance Public methods Also aliased as: visit_TrueClass, visit_FalseClass, visit_Date

str.ord â integer Instance Public methods Return the Integer ordinal of a one-character string. "a".ord #=> 97

class_dir() Instance Public methods Directory where generated class HTML files live relative to the output dir.

call(env) Instance Public methods

gdbm.close â nil Instance Public methods Closes the associated database file.

meth.arity â fixnum Instance Public methods Returns an indication of the number of arguments accepted by a method. Returns a nonnegative integer for methods that take a fixed number of arguments. For Ruby methods that take a variable number of arguments, returns -n-1, where n is the number of required arguments. For methods written in C, returns -1 if the call takes a variable number of arguments. class C def one; end def two(a); end def three(*a); end def four(a, b

parent() Instance Public methods

auth_cram_md5(user, secret) Instance Public methods

time.tv_nsec â int Instance Public methods Returns the number of nanoseconds for time. t = Time.now #=> 2007-11-17 15:18:03 +0900 "%10.9f" % t.to_f #=> "1195280283.536151409" t.nsec #=> 536151406 The lowest digits of to_f and nsec are different because IEEE 754 double is not accurate enough to represent the exact number of nanoseconds since the Epoch. The more accurate value is returned by nsec.
