### Examples

```csharp
using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour
{
    void Start()
    {
        // Prints 10
        Debug.Log(Mathf.FloorToInt(10.0f));
        // Prints 10
        Debug.Log(Mathf.FloorToInt(10.2f));
        // Prints 10
        Debug.Log(Mathf.FloorToInt(10.7f));

        // Prints -10
        Debug.Log(Mathf.FloorToInt(-10.0f));
        // Prints -11
        Debug.Log(Mathf.FloorToInt(-10.2f));
        // Prints -11
        Debug.Log(Mathf.FloorToInt(-10.7f));
    }
