Floats are being rounded when I log?

If I have a list of vector3's I noticed that sometimes the values will get rounded, but i'm not sure why.

I am using UnityEngine.Vector3.

 List<Vector3> verticiesList = new List<Vector3> { };
        
 verticiesList.Add(new Vector3(0.5f, 0.65f, 0));
 Debug.Log(verticiesList[0]);

The result of the log is 0.5,0.7,0.0

how can i give the correct values to mesh.vertices?

I would like to understand why this is happening.

The answer is yes! Unity rounds them to be better readable.

From the Vector3 source code

public override string ToString()
{
    return ToString(null, CultureInfo.InvariantCulture.NumberFormat);
}

public string ToString(string format)
{
    return ToString(format, CultureInfo.InvariantCulture.NumberFormat);
}

public string ToString(string format, IFormatProvider formatProvider)
{
    if (string.IsNullOrEmpty(format))
        format = "F1";
    return UnityString.Format("({0}, {1}, {2})", x.ToString(format, formatProvider), y.ToString(format, formatProvider), z.ToString(format, formatProvider));
}

The default Fixed-point format specifier (F1) rounds the output to 1 fixed digit.

if you want the exact values use e.g.

Debug.Log(verticiesList[0].ToString("G"));

the General format specifier (G) prints up to 7 digits for float values.

If your goal was to store and later restore values e.g. when writing the values to a file etc then rather use G9 instead

When used with a Single value, the "G9" format specifier ensures that the original Single value successfully round-trips.

Already needed this once for a since project.

Using the ToString Method Parameter you can print the floats to what ever decimal place you want:

Debug.Log(verticalList[0].ToString("F6")); //will show 6 decimal places
