Precedence Example

It is easy to make mistakes by forgetting the implications of precedence, the following expression,

    x = a+b/5.0-c**d+1

is equivalent to

    x = ((a+(b/5.0))-(c**d))+1

Likewise the following expression,

    .NOT.A.OR.B.EQV.C.AND.D.OR..NOT.E

is equivalent to

    ((.NOT.A).OR.B).EQV.((C.AND.D).OR.(.NOT.E))

Parentheses can be added to any expression to modify the order of evaluation.
