    Hey all.

    Im trying to input a float like this line:

    print(Mathf.PerlinNoise(0.1,0.0));

    or

    print(Random.Range(0.1,2.0));

    But all im getting is an error:

    Assets/Scripts/LevelManager.cs(14,31): error CS1502: The best overloaded method match for `UnityEngine.Random.Range(float, float)' has some invalid arguments

    if your using C#, your missing an f at the end of the float value.

    print(Mathf.PerlinNoise(0.1f,0.0f));

    print(Random.Range(0.1f,2.0f));

    you dont need to put f at the end of whole numbers. so 0.0 and 2.0 can just be 0 and 2.

    To clarify: C# considers a number with a decimal to be a double by default. The f is a hint to the compiler that it should be considered a float instead.
