Returns the {@link JsonToken#NUMBER double} value of the next token,
consuming it. If the next token is a string, this method will attempt to
parse it as a double using {@link Double#parseDouble(String)}.

@throws IllegalStateException if the next token is not a literal value.
@throws NumberFormatException if the next literal value cannot be parsed
as a double, or is non-finite.
Returns the { @link JsonToken#NUMBER double } value of the next token consuming it . If the next token is a string this method will attempt to parse it as a double using { @link Double#parseDouble ( String ) } .
