round()
round( $d) : \Zxing\Common\Detector\nearest
Ends up being a bit faster than {@link 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 {@link 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 |
Returns
\Zxing\Common\Detector\nearest —{@code int}
