If the bounds of a range node are empty parentheses, then they do not get replaced by their usual s(:nil), but instead are s(:begin).
Foo += bar ^^^^^^^^^^^
Foo &&= bar ^^^^^^^^^^^^
Foo ||= bar ^^^^^^^^^^^^
Foo::Bar = 1 ^^^^^^^^^^^^
Foo::Foo, Bar::Bar = 1 ^^^^^^^^ ^^^^^^^^
Foo::Bar, = baz ^^^^^^^^
Returns self modulo other as a real number.
For integer n and real number r, these expressions are equivalent:
n % r n-r*(n/r).floor n.divmod(r)[1]
See Numeric#divmod.
Examples:
10 % 2 # => 0 10 % 3 # => 1 10 % 4 # => 2 10 % -2 # => 0 10 % -3 # => -2 10 % -4 # => -2 10 % 3.0 # => 1.0 10 % Rational(3, 1) # => (1/1)
Returns self modulo other as a real number.
Of the Core and Standard Library classes, only Rational uses this implementation.
For Rational r and real number n, these expressions are equivalent:
r % n r-n*(r/n).floor r.divmod(n)[1]
See Numeric#divmod.
Examples:
r = Rational(1, 2) # => (1/2) r2 = Rational(2, 3) # => (2/3) r % r2 # => (1/2) r % 2 # => (1/2) r % 2.0 # => 0.5 r = Rational(301,100) # => (301/100) r2 = Rational(7,5) # => (7/5) r % r2 # => (21/100) r % -r2 # => (-119/100) (-r) % r2 # => (119/100) (-r) %-r2 # => (-21/100)
Returns self modulo other as a float.
For float f and real number r, these expressions are equivalent:
f % r f-r*(f/r).floor f.divmod(r)[1]
See Numeric#divmod.
Examples:
10.0 % 2 # => 0.0 10.0 % 3 # => 1.0 10.0 % 4 # => 2.0 10.0 % -2 # => 0.0 10.0 % -3 # => -2.0 10.0 % -4 # => -2.0 10.0 % 4.0 # => 2.0 10.0 % Rational(4, 1) # => 2.0
Returns garbage collector generation for the given object.
class B include ObjectSpace def foo trace_object_allocations do obj = Object.new p "Generation is #{allocation_generation(obj)}" end end end B.new.foo #=> "Generation is 3"
See ::trace_object_allocations for more information and examples.
