-// This routine rounds a double using the "rounding rule", as expressed
-// in _Advanced Engineering Mathematics_ by Erwin Kreyszig, 6th ed.,
-// John Wiley & Sons, Inc., 1988, page 945.
-//
-// Discard the (k+1)th and all subsequent decimals.
-// (a) If the number thus discarded is less than half a unit in the
-// kth place, leave the kth decimal unchanged ("rounding down")
-// (b) If it is greater than half a unit in the kth place, add one
-// to the kth decimal ("rounding up")
-// (c) If it is exactly half a unit, round off to the nearest *even*
-// decimal.
-// Example: Rounding off 3.45 and 3.55 by one decimal gives 3.4 and
-// 3.6, respectively.
-// Rule (c) is to ensure that in discarding exactly half a decimal,
-// rounding up and rounding down happens about equally often,
-// on the average.
