new (source, node_id, location, flags, numerator, denominator)
Source

    # File lib/prism/node.rb, line 15074
    def initialize(source, node_id, location, flags, numerator, denominator)
      @source = source
      @node_id = node_id
      @location = location
      @flags = flags
      @numerator = numerator
      @denominator = denominator
    end

Initialize a new `RationalNode` node.

type ()
Source

    # File lib/prism/node.rb, line 15157
    def self.type
      :rational_node
    end

Return a symbol representation of this node type. See ‘Node::type`.

### Public Instance Methods

=== (other)
Source

    # File lib/prism/node.rb, line 15163
    def ===(other)
      other.is_a?(RationalNode) &&
        (flags === other.flags) &&
        (numerator === other.numerator) &&
        (denominator === other.denominator)
    end

Implements case-equality for the node. This is effectively == but without comparing the value of locations. Locations are checked only for presence.

accept (visitor)

    # File lib/prism/node.rb, line 15084
    def accept(visitor)
      visitor.visit_rational_node(self)
    end

def accept: (`Visitor` visitor) -> void

def inspect -> `String`

numeric ()
Source

    # File lib/prism/node_ext.rb, line 120
    def numeric
      deprecated("value", "numerator", "denominator")

      if denominator == 1
        IntegerNode.new(source, -1, location.chop, flags, numerator)
      else
        FloatNode.new(source, -1, location.chop, 0, numerator.to_f / denominator)
      end
    end

Returns the value of the node as an `IntegerNode` or a `FloatNode`. This method is deprecated in favor of `value` or `numerator`/#denominator.

    end

Returns the value of the node as a Ruby `Rational`.
