You can use math expressions as smart values to insert or set values of numeric custom fields. These can be used anywhere where a custom field can be edited, for example, the Create, Edit and Transition issue actions.

View the smart values available to insert and format numerical values.


In a numeric custom field, you can use an expression to set a value.

1 + 4 sets the field to "5"

To use a math expression in another field, you can insert the value using the below example.

{{#=}}1 + 4{{/}}

// more verbose but more obvious
{{#math}}1 + 4{{/}}

// increase a number by 1

Referencing number fields

To perform calculations with numeric custom fields in Jira, you can reference the field as a smart value in your calculation.

{{#=}}3.2 * {{issue.My Number field}} + 43{{/}}

You can add two custom fields using the below example.

{{#=}}{{issue.Sale Amount}} * {{issue.Discount}}{{/}}
