Hi all.
I need to create a complex rpn expression. In two words, it calculates a value,
everything is easy. But one small problem. In expression formula I need to
devide one value by another. And the devider sometimes could be zero. As far as
i know, rrd rpn sets the result of devision by zero as INFINITY. But in that
case i need to set result as 0. So i try such RPN expression:
{my_result_value_which_could_be_infinity},DUP,ISINF,EXC,0,EXC,IF
But that doen't work. There is no graph at all shown. Afaik it means, that
there is a mistake in rpn expression. What's wrong with that expression?
Alex.
