What Does 1F represent in the following code?

Question

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:

    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);
    }
}

And the speed of cycling is depends on 1F 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

Answer 1

In C#, a lowercase f after a number indicates that the value should be treated as a float.

By multiplying this by the deltaTime value, it's rotating either 1 degree or 1 radian per second. I'm unfamiliar with Unity and can't speak authoritatively on the subject.
