#define CPPAD_ZDOUBLE_OTHER_COMPARE_OPERATOR	(		op,
			op_switch
	)

Value:

inline bool operator op(const double& x, const zdouble& z)    \
     {    return z op_switch x; }

Define a comparison operator that is not a member because the double operand is on the left.

Convert it to the case where the double operand is on the right by by using op_switch instead of op.
