# Class: IntValue

> A container object for a single integer.

## Description

Stores a single signed [64-bit integer](/docs/en-us/luau/numbers.md#int64). The
highest allowed value is 2^63-1 or around 9.2 quintillion (9.2^18). Attempting
to store larger numbers causes an
[integer overflow](https://en.wikipedia.org/wiki/Integer_overflow). The lowest
allowed value is -2^63. Practically, however, working with integers larger
than 2^53 (9^15) causes loss of precision since Luau uses double-precision
floating-point to store numbers.

It's possible to store values between 2^53 and 2^63-1 using the
[Properties](/docs/en-us/studio/properties.md) window since it uses strings to
pass data to the engine, but manipulating large values via Luau scripts
results in loss of precision and rounding as mentioned above.

The main advantage of using **IntValue** lies in its rounding of values to the
nearest integer, with halfway cases rounded away from 0. For values outside of
this range, use [NumberValue](/docs/reference/engine/classes/NumberValue.md) instead.

Like all [ValueBase](/docs/reference/engine/classes/ValueBase.md) objects, this single value is stored in the
[Value](/docs/reference/engine/classes/IntValue.md) property. The `Changed` event fires with the new
value being stored in the object, instead of a string representing the
property being changed.

## Properties

### Property: IntValue.Value

```json
{
  "type": "int64",
  "access": "ReadWrite",
  "security": {
    "read": "None",
    "write": "None"
  },
  "serialization": {
    "can_load": true,
    "can_save": true
  },
  "thread_safety": "ReadSafe",
  "category": "Data",
  "simulationAccess": true
}
```

Used to hold an integer.

## Events

### Event: IntValue.Changed

**Signature:** `IntValue.Changed(value: int64)`

Fires whenever the [IntValue.Value](/docs/reference/engine/classes/IntValue.md) changes. It runs with the new
value being stored in the argument object, instead of a string
representing the property being changed.

Listening for the `Changed` signal can be useful in games that use
`IntValues` to track values like leaderboard statistics or item prices.

*Security: None*

**Parameters:**

| Name | Type | Description |
|------|------|-------------|
| `value` | `int64` | The new value after the change. |

**How to Use IntValue.Changed**

The below example, assuming all referenced objects existed, would print the
IntValue's new value each time it changed. In the example below it would
print 20.

```lua
local value = Instance.new("IntValue")
value.Parent = workspace

local function onValueChanged(newValue)
	print(newValue)
end

value.Changed:Connect(onValueChanged)

value.Value = 20
```

**Expected output:** "20"

### Event: IntValue.changed

**Signature:** `IntValue.changed(value: int64)`

> **Deprecated:** This deprecated event is a variant of [IntValue.Changed](/docs/reference/engine/classes/IntValue.md) which should be used instead.

*Security: None*

**Parameters:**

| Name | Type | Description |
|------|------|-------------|
| `value` | `int64` |  |
