JIRA Misc Custom Fields plugin - formatting?

I'm using the JIRA Misc Custom Fields plugin within Confluence to calculate some things between other custom fields. The result of the equation is a float, which display just fine, however I want to be able to format the output so that it only shows 2 decimal places.

Not being a java bod in any shape or form, could somebody tell me how I would force the format to 2 decimal places please?

Figured it out - the code is not what I am intending to do, just a simple way of proving that I can do something more complex. =)

<!-- @@Formula: 

import java.text.DecimalFormat;
import java.text.NumberFormat;

double estDiff = 0; 

estDiff = issue.get("timeestimate");
estDiff = estDiff / 3600;

NumberFormat formatter = new DecimalFormat("#0.00");

return formatter.format(estDiff);

It's not something you can do in the UI I'm afraid.

If you were willing to pull apart the plugin and recompile it, you can do it with a bit of "velocity" - these are templates which determine the html that comes out. The result you're seeing is probably rendered with a simple "if $value, then show $value" type line of code, which you could change to "if $value, then show $value.format("%.2g%n") "

Or you might try injecting some javascript to format it as the browsers render it (I'm less sure on the code for that)

The documentation for the plugin states it can be formatted ...

Custom formatting

You can also specify custom formatting for the value of the Calculated Number field. In the Description field, add your formatting formula using the following syntax:

<!-- @@Format: formula goes here -->

The formula itself is a Java-style expression that can reference the value returned by the formula using the value variable. You can also use the numberTool object to format the number value:


To display an icon to the left of the field value depending on the field value:

<!-- @@Format:
if (value > 21)
return "<img src='/images/icons/priority_trivial.gif'> "+numberTool.format(value);
else if (value >= 10)
return "<img src='/images/icons/priority_major.gif'> "+numberTool.format(value);
return "<img src='/images/icons/priority_blocker.gif'> "+numberTool.format(value);

I just can't figure it out - at least, not in the amount of time I have :-(
