# operator *

> Multiplies a vector by a number.

## Definition

* **Type:** Operator
* **Namespace:** [UnityEngine](/engine/6000.7/script-reference/unityengine.md)
* **Assembly:** UnityEngine.CoreModule

## operator \*(Vector3, float)

Multiplies a vector by a number.

```csharp
public static Vector3 operator *(Vector3 a, float d)
```

### Parameters

**** (\[Vector3]\(/engine/6000.7/script-reference/unityengine/vector3)): The vector to multiply by `d`.**** (\[float]\(https\://learn.microsoft.com/dotnet/api/system.single)): The number to multiply `a` by.

### Returns

| Type                                                              | Description |
| ----------------------------------------------------------------- | ----------- |
| [Vector3](/engine/6000.7/script-reference/unityengine/vector3.md) |             |

### Remarks

Multiplies each component of `a` by a number `d`.

### Examples

```csharp
// make the vector twice longer: prints (2.0,4.0,6.0)
using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour
{
    void Example()
    {
        print(new Vector3(1.0f, 2.0f, 3.0f) * 2.0f);
    }
}
```

## operator \*(float, Vector3)

Multiplies a vector by a number.

```csharp
public static Vector3 operator *(float d, Vector3 a)
```

### Parameters

**** (\[float]\(https\://learn.microsoft.com/dotnet/api/system.single)): The number to multiply by `a`.**** (\[Vector3]\(/engine/6000.7/script-reference/unityengine/vector3)): The vector to multiply `d` by.

### Returns

| Type                                                              | Description |
