Last modified: March 28, 2025

Introduction

This document describes the function that converts a string to a value that is of data type Integer/Long.

parseInteger

Takes a string and parses it to an Integer/Long.

Input Parameters

The input parameters are described in the table below:

Value	Type
The string to parse	String
Default value (optional)	Integer/Long

A default value can be specified to handle parsing errors. If no default value is provided, an error will occur if the string is not a number or if the parsed value is not within the range of valid values for an Integer/Long. The range of valid values for an Integer/Long can be found in this table of supported data types.

Output

The output is described in the table below:

Value	Type
An Integer/Long if it is possible to parse it from the string. If the string cannot be parsed to an Integer/Long, the default value will be returned. If no default value is provided, an error will occur.	Integer/Long

Examples

The examples below illustrate which value the expression returns:

If you use the following input:
```
parseInteger('42')
```
the output is:
```
42
```
If you use the following input:
```
parseInteger('not_an_integer', 42)
```
the output is:
```
42
```
