# Value Formatting [#](https://gudhub.com/docs/understanding-gudhub/data/value-formatting/#value-formatting)

Lots of gh-element store some values. Despite of usual databases, GudHub has no column types.

> All values in GudHub are stored as a **string type** data.

That is why, we have introduced some standards of data recording. There are lots of gh-elements that contain some data called _field value_. The each value is formatted according to the element where it is stored.

## Data Presentation [#](https://gudhub.com/docs/understanding-gudhub/data/value-formatting/#data-presentation)

Since all data is stored as a string type, its presentation based on dividers. That means, different types of elements has different dividers or at their absence.

### Single [#](https://gudhub.com/docs/understanding-gudhub/data/value-formatting/#single)

Any single value is stored as a string data **without any dividers**.

Copy

```json
{
    "field_value": "John Dow"
}
```

### Value Range [#](https://gudhub.com/docs/understanding-gudhub/data/value-formatting/#value-range)

There lots of element which has two values related to each other. They may circumscribe some range or denote coordinates. Such values are stored separated by a **colon**.

The current divider is inherent to such elements:

-   [Range](https://gudhub.com/docs/gh-elements/range-element/)
-   [GPS Coords](https://gudhub.com/docs/gh-elements/gps-coords/)
-   [Date](https://gudhub.com/docs/gh-elements/date/)

The example of values of such elements:

Copy

```json
{
    "field_value": "19.7633057:96.07851040000001"
}
```

### Multiple [#](https://gudhub.com/docs/understanding-gudhub/data/value-formatting/#multiple)

Some of elements in GudHub contains the multiple value. This type of value has its own divider.

> All their values will be stored in one string separated by a **comma**.

Copy

```json
{
    "field_value": "John Dow, Johana Dow"
}
```

## Types Of Value [#](https://gudhub.com/docs/understanding-gudhub/data/value-formatting/#types-of-value)

Besides of presentation, values can be divided by types. It is because every element has its own specification, so their data must be different.

### Numbers [#](https://gudhub.com/docs/understanding-gudhub/data/value-formatting/#numbers)

All values are stored as a string type data. The number is not an exception.

Copy

```json
{
    "field_value": "3"
}
```

Generally speaking, the number does not have any features other than floating numbers.

#### **Float** [#](https://gudhub.com/docs/understanding-gudhub/data/value-formatting/#float)

Floating point values are stored with a **point**. If user enters float value with the comma it will be saved as _NaN_.

Copy

```json
{
    "field_value": "5.00"
}
```

### Boolean [#](https://gudhub.com/docs/understanding-gudhub/data/value-formatting/#boolean)

The boolean values in GudHub are stored as **1 or 0**. This is because all data is stored as string type data and numbers 1, 0 take less memory than words true, false.

Copy

```json
{
    "field_value": "1"
}
```

### Option [#](https://gudhub.com/docs/understanding-gudhub/data/value-formatting/#option)

All options elements store the numbers of the selected option. Like the previous value type, the current one uses numbers to use less memory.

Copy

```json
{
    "field_value": "3"
}
```

Such type of value is used in these gh-elements:

-   [Color List](https://gudhub.com/docs/gh-elements/color-list/)
-   [Text Options](https://gudhub.com/docs/gh-elements/options-element/)
-   [Radio Button](https://gudhub.com/docs/gh-elements/radio-button/)
-   [Radio Icon](https://gudhub.com/docs/gh-elements/radio-icon/)

### Date and Time [#](https://gudhub.com/docs/understanding-gudhub/data/value-formatting/#date-and-time)

The date and time values are stored in **milliseconds**. Milliseconds counted since January 1, 1970. All dates after this date are positive values, all dates before are negative values.

Date and time after 1970. `Jul 18 2022 21:00:29`:

Copy

```json
{
    "field_value": "1658178029973"
}
```

Date and time before 1970. `Jun 16 1917 02:59:30`:

Copy

```json
{
    "field_value": "-1658178029973"
}
```

### References [#](https://gudhub.com/docs/understanding-gudhub/data/value-formatting/#references)

Items in GudHub can be linked using special generated references. It is the standard way to applications together. The reference consists of the source application ID and a specific item ID, separated by a **point**.

Copy

```json
{
    "field_value": "29000.3123100"
}
```

It can mostly be seen as the value of the [Item Reference](https://gudhub.com/docs/gh-elements/item-reference/) parameter, but it is also used to configure different elements.

### Files [#](https://gudhub.com/docs/understanding-gudhub/data/value-formatting/#files)

The files are contained in the file list. Each file has its own **ID**, and it is this ID that is contained in some elements. You can get the file itself using his it.

Copy

```json
{
    "field_value": "952766"
}
```

### Documents [#](https://gudhub.com/docs/understanding-gudhub/data/value-formatting/#documents)

The JSON documents in GudHub have their own IDs. It is this identifier that some elements store as a value:

Copy

```json
{
    "field_value": "62e0de10b3a26926b24136ef"
}
```

One of elements that contains such value is [Quiz](https://gudhub.com/docs/gh-elements/quiz/).

### Color [#](https://gudhub.com/docs/understanding-gudhub/data/value-formatting/#color)

The selected colors are contained in elements as a appropriate **hex code**.

Copy

```json
{
    "field_value": "#ffffff"
}
```

### Phone [#](https://gudhub.com/docs/understanding-gudhub/data/value-formatting/#phone)

The phone is an element whose value have a special divider. The value format of the phone depends of the availability of the country code and the extension. They can be added in [Phone element settings](https://gudhub.com/docs/gh-elements/phone/).

> The country code and extension number are divided from the main number by **point**.

The full phone value is looks like this:

Copy

```json
{
    "field_value": "1.4842918926.456"
}
```

But the number without that additions have no dividers.
