### Public Class Methods

new(source, node_id, location, flags, numerator, denominator) click to toggle source

Initialize a new `RationalNode` node.

    # File 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

type() click to toggle source

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

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

### Public Instance Methods

===(other) click to toggle source

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

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

numeric() click to toggle source

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

    def numeric
      deprecated("value", "numerator", "denominator")

      if denominator == 1
