Float to Int Cast strange behaviour

Hi, i have a problem with a strange cast behaviour. if i try this:

 float a = 5.112;
 int b = (int ) a;

it works fine and i get b= 5;

but if im using Vector2:

 Vector2 vec2 = new Vector2(5.112f, 123.2f);
 
 int a = (int) vec2.x;

i get 5112 instead of 5;

i get the same result if using

 Math.Floor(vec2.x);

also get 5112 instead of 5.

i hope someone can explain whats happening here and how can i solve this

I don't have this problem. How do you use the output?

 private void Start()
 {
     float a = 5.112f;
     int b = (int)a;

     Vector2 vec2 = new Vector2(5.112f, 123.2f);

     int c = (int)vec2.x;
     double d = System.Math.Floor(vec2.x);

     Debug.Log(a + " " + b + " " + c + " " + d);
 }

In the console, I get 5,112 5 5 5

You're right. It seems like the problem occurs when I fill the Vector2 with data from .obj file. Then I get this kind of float in the Console: 0,05122E+02 Maybe this the reason?
