# Problem with number rounding down rather than showing decimal points

Current system has the following code to compute the average of 5 different number. All have a default value of 0. For example:4+7+4+7+4=26 / 5 =5.2 but system shows 5. Please help how to change my code:

<!-- @@Formula:
double val = 0;
double weight = 0;
val = (
(issue.get("customfield_12900") != null ? Integer.parseInt(issue.get("customfield_12900").toString()) : 0) +
(issue.get("customfield_12901") != null ? Integer.parseInt(issue.get("customfield_12901").toString()) : 0) +
(issue.get("customfield_12902") != null ? Integer.parseInt(issue.get("customfield_12902").toString()) : 0) +
(issue.get("customfield_12903") != null ? Integer.parseInt(issue.get("customfield_12903").toString()) : 0) +
(issue.get("customfield_12904") != null ? Integer.parseInt(issue.get("customfield_12904").toString()) : 0)
) / 5;
return val;
-->
<!-- @@Format:
numberTool.format("#0.00",value);

Foremost, this is Misc Custom Field's syntax but you marked JIRA Cloud... I don't believe that Misc Custom Fields is available in JIRA Cloud.

Second, you are using "Integer.parseInt..." Integers by design do NOT handle decimal points. Please modify your code to use a proper type instead of discarding decimals. If you'd like help with your script, please plainly state your use-case.

Further to the comment from @Steven Behnke He is correct that the values you are retrieving are all integers hence why when you do the calculation it returns an integer. I believe although I am not an expert in the formats for Misc Custom Fields syntax that the syntax you should be using is

<!-- @@Formula:
double val = 0;
double weight = 0;
val = (
(issue.get("customfield_12900") != null ? float.parseInt(issue.get("customfield_12900").toString()) : 0) +
(issue.get("customfield_12901") != null ? float.parseInt(issue.get("customfield_12901").toString()) : 0) +
(issue.get("customfield_12902") != null ? float.parseInt(issue.get("customfield_12902").toString()) : 0) +
(issue.get("customfield_12903") != null ? float.parseInt(issue.get("customfield_12903").toString()) : 0) +
(issue.get("customfield_12904") != null ? float.parseInt(issue.get("customfield_12904").toString()) : 0)
) / 5;
return val;

I hope this helps point you in the right direction even if the exact format of the commands is slightly out.

Thanks Phil; It's been quite some time since I've written a calculated field with that add-on. :)

It would have been enough to divide by 5.0 instead of 5.

int / int = int

int / float = float
