InvalidCastException with .net datatypes but not with UnityEngine.Object

Question

The following returns the following error: Line 11: InvalidCastException: Cannot cast from source type to destination type.

It works perfectly with anything that inherits from UnityEngine.Object. I don't understand how to prevent this from happening with .net datatypes.

void Start () {

     float[] f = new float[5];
     f[0] = 4.5f;
     Test(f);
 }

 void Test(object t)
 {
     if (t is Array)
     {
         Debug.Log("isarray");
         object[] a = (object[])t;
         if (a[0] is float)
         {
             Debug.Log("isfloat");
         }
     }
 }

Correct, float didn't extends object.

You need te take a read about basic types, arrays and casting. Until you didn't understand it is better to use a more complex collection like ArrayList. (link)

Edited

I found the oficial docs about the problem, if you wish to get a deep understand
