C# How can create a list of floats from different types of structs?

For the project I'm currently working I keep running into an issue where float values return in the negative. I've got a block that can convert them to positives.

     public float positivefloat(float num1)
     {
         float result;
 
         if (num1 < 0)
         {
             result = num1 * -1;
         }
         else
         {
             result = num1;
         }
         return result;
     }
 

The issue is that i still have to type "positivefloat("variable name"); for each individual float i need in the positive. so if i have a Vector2, Vector3, or Quaternion, I have to reference each axis manually.

How would i go about writing a method to check to see w$$anonymous$$ch type the reference is(float, Vector2, Vector3, Quaternion) and pull all of the corresponding axis floats into a list. then use a foreach to execute positivefloat on each item in the list, then return the list in all positives?
