# Value formulas

You can define a business rule that sets a field's value based on the evaluation of a JavaScript formula.

In this topic:

## Overview

The JavaScript formula can consist of a single JavaScript expression on a single line. The result of the expression must match the value type of the field that is being set. There is no validation of the type match. The supported functions, methods, and operators are listed in the sections below.

As you type the expression in the formula box, autocomplete suggests the right fields and functions.

Namespace conventions: Functions are accessed through namespaces such as Math, Date, DateUtils, MathUtils, CollectionUtils, and Context. String and collection operations can be called directly on field values using dot notation.

## Comparison and logical operators

The following comparison and logical operators are supported for evaluating conditions.

Operator | Example | Description
--- | --- | ---
== | entity.story_points.value == entity.actual_story_points.value | Equality operator. Note: For date fields, use DateUtils.isEqual() instead.
!= | entity.story_points.value != entity.actual_story_points.value | Inequality operator. Note: For date fields, use DateUtils.isEqual() with negation instead.
> | entity.story_points > entity.actual_story_points | Greater than
< | entity.story_points < entity.actual_story_points | Less than
>= | entity.story_points >= entity.actual_story_points | Greater than or equal to
<= | entity.story_points <= entity.actual_story_points | Less than or equal to
&& | (entity.story_points > entity.actual_story_points) && (entity.bucket_rank < entity.udf) | Logical AND. Returns true only if both conditions are true.
|| | (entity.story_points > entity.actual_story_points) || (entity.bucket_rank < entity.udf) | Logical OR. Returns true if at least one condition is true.
! | !(entity.story_points > entity.actual_story_points) | Logical NOT. Negates a boolean condition.
? : | (entity.udf > entity.udf.originalValue) ? entity.udf : entity.udf.originalValue | Ternary operator. Returns the first value if the condition is true, the second value if false.

## Math operations

The following math functions and operators are supported for numeric calculations.

Function or operator | Example | Description
--- | --- | ---
+ | entity.story_points + entity.bucket_rank_udf | Addition
- | entity.story_points - entity.actual_story_points | Subtraction
* | entity.story_points * entity.bucket_rank_udf | Multiplication
/ | entity.story_points / entity.bucket_rank_udf | Division
% | (entity.story_points % entity.actual_story_points) | Modulo. Returns the integer remainder of dividing the two operands. For example, 12 % 5 returns 2.
Math.min(e1, e2, ...) | Math.min(entity.story_points, entity.actual_story_points, entity.udf) | Returns the smallest of the given numeric expressions.
Math.max(e1, e2, ...) | Math.max(entity.story_points, entity.actual_story_points, entity.udf) | Returns the largest of the given numeric expressions.
Math.abs(expression) | Math.abs(entity.udf) | Returns the absolute (non-negative) value of the expression.
Math.round(expression) | Math.round(entity.udf) | Rounds a value to the nearest integer.
Math.floor(expression) | Math.floor(entity.story_points / entity.actual_story_points) | Rounds the value down to the nearest integer.
Math.ceil(expression) | Math.ceil((entity.score_udf + entity.business_udf) * entity.story_points) | Rounds the value up to the nearest integer.
Math.trunc(expression) | Math.trunc((entity.score_udf - entity.business_udf) * entity.story_points) | Returns the integer part of the expression, removing any fractional component.
Math.pow(x, y) | Math.pow(2, 3) | Returns x raised to the power of y (x^y). Example: Math.pow(2, 3) returns 8.
MathUtils.avg(t1, t2, ...) | MathUtils.avg(entity.story_points, entity.estimated_time, entity.initial_estimation) | Returns the average (mean) value of the provided numeric terms.

## String operations

The following string methods are supported for manipulating and analyzing text values. All string methods are called directly on a string field using dot notation.

Method | Example | Description
--- | --- | ---
substring(start, end) | entity.string_udf.substring(3, 8) | Extracts a substring from the start index up to (but not including) the end index.
substr(start, length) | entity.string_udf.substr(2, 5) | Extracts a substring starting at the start index for the specified length.
toUpperCase() | entity.string_udf.toUpperCase() | Converts all characters in the string to uppercase.
toLowerCase() | entity.string_udf.toLowerCase() | Converts all characters in the string to lowercase.
trim() | entity.string_udf.trim() | Removes whitespace from both the beginning and end of a string.
trimStart() | entity.string_udf.trimStart() | Removes whitespace from only the beginning of a string.
trimEnd() | entity.string_udf.trimEnd() | Removes whitespace from only the end of a string.
concat(text1, text2, ...) | entity.string_udf.concat(" ", "Nice try") | Joins two or more strings together.
includes(substring) | entity.string_udf.includes("search term") | Checks if a string contains a specified substring. Returns true or false.
indexOf(substring) | entity.string_udf.indexOf("search term") | Returns the index of the first occurrence of a substring, or -1 if not found.

## Length property

The length property works for strings and collections.

Property | Example | Description
--- | --- | ---
length | entity.string_udf.length entity.product_areas.length | Returns the size of a field's value. The meaning depends on the field type: String fields: Returns the number of characters in the string. Collections and multi-valued fields: Returns the number of items in the collection (e.g., product areas, teams, multi-select lists).

## Original value property

The originalValue property allows you to access a field's previous value before the current update.

Property | Example | Description
--- | --- | ---
originalValue | (entity.initial_estimate > entity.initial_estimate.originalValue) ? entity.initial_estimate : entity.initial_estimate.originalValue | Gets the value that was set to the field before the current update. Note: Available only for Integer, String, and Date field types. Use case: Preserve the maximum value during updates. If an update attempts to set a lower value than the current one, ignore the update and retain the higher stored value.

## Current user properties

The following properties provide access to current user information.

You can read the following properties of the currentUser object: email, fullName, id, name, roles

Property | Example | Description
--- | --- | ---
Context.currentUser.email | entity.owner == Context.currentUser.email | Returns the email address of the currently logged-in user.
