title: What Does 1F represent in the following code?
body: <p>I'm learning Unity 5 and I know nothing about Programming. But I have watched a tutorial on "How to make a Day/Night Cycle" in Unity and the tutor wrote this script to cycle between moon and sun.. Here's the code:</p>
  
  <pre><code>    using UnityEngine;
  using System.Collections;
  
  public class sun : MonoBehaviour {
  
      // Use this for initialization
      void Start () {
  
      }
  
      // Update is called once per frame
      void Update () {
          transform.RotateAround(Vector3.zero, Vector3.right, 1f * Time.deltaTime);
          transform.LookAt(Vector3.zero);
      }
  }
  </code></pre>
  
  <p>And the speed of cycling is depends on <strong>1F</strong> which we can change the any number.. But I don't know how long does it take to do 1F rotation between sun and moon! So can you tell me this number in something like seconds or minutes ? So I can be able to set it myself to a custom duration. Thanks in advance </p>
