Hi, any thoughts on this ? I really think it's counter intuitive ? Thanks, Sebastian Haase On Tuesday 05 July 2005 17:34, Sebastian Haase wrote:
Hi,
I was very surprised when I got this warning:
a = na.arange(4)-2 na.where(a != 0,1./a, 999)
Warning: Encountered divide by zero(s) in divide [ -0.5 -1. 999. 1. ]
Then I realized that this is generally referred to as (not) "short circuiting" (e.g. in the case of the '?:'-C-operator, the middle part never gets evaluated at all if the first part evals to 0 )
Especially annoying was this because (for debugging) I had set this
error-mode:
na.Error.setMode(dividebyzero="error")
My questions are: a) Did other people encounter this problem ? b) What is the general feeling about this actually being a "problem" ? c) Could this (at all possible) be implemented differently ?
Thanks, Sebastian Haase
