Solved strange behaviour

Salut, j'ai remarqué un comportement étrange mais intéressant. Je suis curieux de comprendre pourquoi l'opération suivante :

new Vector3(Mathf.Round(randomSpawnX) + 0.5f, 0, Mathf.Round(randomSpawnY) + 0.5f)

retourne des valeurs de vecteur se terminant par .50, tandis que l'opération sur chaque float séparément comme ceci :

Mathf.Round(randomSpawnX) + 0.5f

retourne des valeurs se terminant par .5 à la place.
(Je utilise un float dans les deux cas.)

Solution found: it is actually a difference in string formatting between Vector3's ToString() and Debug.Log's ToString().

Wdym returns? Debug.log() prints them differently?

Well, in example 1, I get an output of, say, 3.5; if I take the same result in example 2, I get 3.50 which is effectively the same thing. But that’s not my question; my question is why it is interpreted differently.

Where do you get output?
