[RESOLVED]BC calculation for floating (invalid arithmetic operator )
Hi,
I wish to compare the CPU LOAD 1 min with 5mins and 15mins.
If 1 min's CPU LOAd spike 3% compare to 5 mins or 15 mins CPU Load, it is warning.
If 1 min's CPU LOAd spike 5% compare to 5 mins or 15 mins CPU Load, it is critical.
However I received following code error, I google it and tried few method it still the same.
May I know which part could be wrong?

cmp(3).
PARAMETERS
o $str1
- The first string.
o $str2
- The second string.
RETURN VALUES
Returns < 0 if $str1 is less than $str2; > 0 if $str1 is greater than $str2, and 0 if they are equal.
