How to format Number values in Email Templates

Values of Number custom fields or number constants may be formatted in email templates in various ways.

The key to number formatting is the $!number variable which is an instance of the NumberTool Jira API class.

NumberTool provides buit-in styling for formatting numbers but also provides access to Java NumberFormat API which provides ultimate formatting capabilities.

Below is an example of formatting the value of a number field called "My Number Field" in various styles.

#set ($numberValue = $!issue.getCustomFieldValue("My Number field"))

Integer: $!number.format("integer",$!numberValue)

Number: $!number.format("number",$!numberValue)

Currency: $!number.format("currency",$!numberValue)

Percent: $!number.format("percent",$!numberValue)

Default: $!number.format("default",$!numberValue)

Below is an example of using Java's NumberFormat to render the number value in Japan's currency:

#set ($numberValue = $!issue.getCustomFieldValue("My Number field"))
#set($numberFormat = $!number.getNumberFormat("currency", $!templateSupport.getLocale("jp_JP")))

Currency in Japan: $!numberFormat.format($numberValue)
