round

Rounds argument x to the nearest integer, but round halfway cases away from zero, (regardless of the current rounding direction), instead of to the nearest even integer like rint.

Example: Round (double):

public static int main (string[] args) {
	// Output:
	//  ``round (1.3) =  1.0``
	//  ``round (1.4) =  1.0``
	//  ``round (1.5) =  2.0``
	//  ``round (1.6) =  2.0``

	print ("round (%.1lf) =  %.1lf\n", 1.3, Math.round (1.3));
	print ("round (%.1lf) =  %.1lf\n", 1.4, Math.round (1.4));
	print ("round (%.1lf) =  %.1lf\n", 1.5, Math.round (1.5));
	print ("round (%.1lf) =  %.1lf\n", 1.6, Math.round (1.6));

	return 0;
}
