public static int round(float d)
```
    Ends up being a bit faster than Math.round(float). This merely rounds its argument to the nearest int, where x.5 rounds up to x+1. Semantics of this shortcut differ slightly from Math.round(float) in that half rounds down for negative values. -2.5 rounds to -3, not -2. For purposes here it makes no difference.
    
    Parameters:
    
    d - real value to round
    
    Returns:
    
    nearest int
