Simple Division
|
ok, what am I doing wrong? I need to calculate (divide) 2 numbers and then multiply by 100 to get the average. Kix can add, subtract and multiple but can't divide?
$foo = 5
$bar = 10
$foo + $bar
- returns 15
$foo - $bar
- returns -5
$foo * $bar
- returns 50
... but ... $foo / $bar
- returns ... zero?

It's partly the way you defined your numbers and it's the way Kix generally handles numbers. It can be worked around though.
FTR, if you had tried $bar / $foo it would have worked.
You can define a number as Double to avoid the problem. So instead of 5 you can define as 5.0. Or you can use the function CDBL to do it, ie CDBL($foo).

Re: Simple Division

I understand what you are saying. My data is being retrieved via a WMI query and the calculation is actually part of a script to determine the percentage of free disk space. Casting the value as Double (CDBl) was probably the only function I didn't try.
... one moment, please ...

Casting the value(s) as CDBL worked!
... I think that is the only options I didn't try before!
I knew it had to be something stupid simple.
As always, thank you @allen

$data = WmiQuery(get disk things...)
$FreePct = 1.0 * $data.free / $data.size
Multiplying by 1.0 FIRST tells Kix that the entire operation should use double-precision math without calling a function or changing the values.
Adding 0.0 to an add/subtract has the same net effect.

BTW - What platform are you using for monitoring, or is this just for information gathering and reporting?
