I ethically borrowed some source code and it doesn't work

public static float Min(params float[] values)
{
    int num = values.Length;
    if (num == 0)
    {
        return 0f;
    }

    float num2 = values[0];
    for (int i = 1; i < num; i++)
    {
        if (values[i] < num2)
        {
            num2 = values[i];
        }
    }

    return num2;
}

public static float Min(params float[] values)
{
    int num = values.Length;
    if (num == 0)
    {
        return 0f;
    }

    float num2 = values[0];
    for (int i = 1; i < num; i++)
    {
        if (values[i] < num2)
        {
            num2 = values[i];
        }
    }

    return num2;
}
