# Supported Data Types

## Data types in Decision Tables

All data in a data table are stored as string values and are **automatically casted when needed**. Therefore, you don't need to specify any data format for your \*\*\*\* [**input and output** ](/doc/~/changes/VuchuDyabVa3NSXAKjpZ/decision-tables/input-and-output.md)models. The automatic casting of conditions and results is described in the following sections.

{% hint style="info" %}
**The decimal separator is always a dot - "."**
{% endhint %}

### Condition Data Types

The conditions can be made using the following scalar data types:

* Number
* Boolean
* String
* Date

#### Conditions

![](/files/-MW-ScBcFqLpmLainnqk)

#### Solver Request Data

```javascript
// 2.31
{
  "inputData": 2.31 OR "2.31"
}

// true
{
  "inputData": true
}

//false
{
  "inputData": false
}

// hello world
{
  "inputData": "hello world"
} 

// 17/13/2021 13:17 GMT:-9:00
{
"inputData": {"date":"2021-03-17","time":"13:17","timezone":"-09:00"}
}
// DATE TIME INPUT AS ISO-8601
{
"inputData": "2021-03-17T13:17-09:00"
}
// OR ANY PARSEABLE DATE STRING
{
"inputData": "2021-03-17, 13:17 -09:00"
}
// <empty>
{}
OR
{
  "inputData": ""
}
```

### Result Data Types

Calling [**Solver API**](/doc/~/changes/VuchuDyabVa3NSXAKjpZ/api/rule-solver-api.md#solve-rule) returns an array of results according to the decision table setup. Response values are **automatically cast** to:

* Boolean
* Number OR Float
* String
* Date
* JSON Object
* JSON Arrays

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.decisionrules.io/doc/~/changes/VuchuDyabVa3NSXAKjpZ/decision-tables/data-types.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
