Precedence Examples

In our example, we would want the following declarations:

%left '<'
%left '-'
%left '*'

In a more complete example, which supports other operators as well, we would declare them in groups of equal precedence. For example, '+' is declared with '-':

%left '<' '>' '=' NE LE GE
%left '+' '-'
%left '*' '/'

(Here NE and so on stand for the operators for "not equal" and so on. We assume that these tokens are more than one character long and therefore are represented by names, not character literals.)
