+ *
+ *	Cube root, long double precision
+ *
+ *
+ *
+ * SYNOPSIS:
+ *
+ * long double x, y, cbrtl();
+ *
+ * y = cbrtl( x );
+ *
+ *
+ *
+ * DESCRIPTION:
+ *
+ * Returns the cube root of the argument, which may be negative.
+ *
+ * Range reduction involves determining the power of 2 of
+ * the argument.  A polynomial of degree 2 applied to the
+ * mantissa, and multiplication by the cube root of 1, 2, or 4
+ * approximates the root to within about 0.1%.  Then Newton's
+ * iteration is used three times to converge to an accurate
+ * result.
+ *
+ *
+ *
+ * ACCURACY:
+ *
+ *                      Relative error:
+ * arithmetic   domain     # trials      peak         rms
+ *    IEEE       -8,8       100000      1.3e-34     3.9e-35
+ *    IEEE    exp(+-707)    100000      1.3e-34     4.3e-35

 # Given the above, what's chosen for year-round use is:
 #	CST	for any place operating at a GMTOFF of 9:30
 #	WST	for any place operating at a GMTOFF of 8:00
 #	EST	for any place operating at a GMTOFF of 10:00
 
+# From Paul Eggert (2001-04-05), summarizing a long discussion about "EST"
+# versus "AEST" etc.:
+#
+# I see the following points of dispute:
+#
+# * How important are unique time zone abbreviations?
+#
+#   Here I tend to agree with the point (most recently made by Chris
+#   Newman) that unique abbreviations should not be essential for proper
+#   operation of software.  We have other instances of ambiguity
+#   (e.g. "IST" denoting both "Israel Standard Time" and "Indian
+#   Standard Time"), and they are not likely to go away any time soon.
+#   In the old days, some software mistakenly relied on unique
+#   abbreviations, but this is becoming less true with time, and I don't
+#   think it's that important to cater to such software these days.
+#
+#   On the other hand, there is another motivation for unambiguous
+#   abbreviations: it cuts down on human confusion.  This is
+#   particularly true for Australia, where "EST" can mean one thing for
+#   time T and a different thing for time T plus 1 second.
+#
+# * Does the relevant legislation indicate which abbreviations should be used?
+#
+#   Here I tend to think that things are a mess, just as they are in
+#   many other countries.  We Americans are currently disagreeing about
+#   which abbreviation to use for the newly legislated Chamorro Standard
+#   Time, for example.
+#
+#   Personally, I would prefer to use common practice; I would like to
+#   refer to legislation only for examples of common practice, or as a
+#   tiebreaker.
+#
+# * Do Australians more often use "Eastern Daylight Time" or "Eastern
+#   Summer Time"?  Do they typically prefix the time zone names with
+#   the word "Australian"?
+#
+#   My own impression is that both "Daylight Time" and "Summer Time" are
+#   common and are widely understood, but that "Summer Time" is more
+#   popular; and that the leading "A" is also common but is omitted more
+#   often than not.  I just used AltaVista advanced search and got the
+#   following count of page hits:
+#
+#     1,103 "Eastern Summer Time" AND domain:au
+#       971 "Australian Eastern Summer Time" AND domain:au
+#       613 "Eastern Daylight Time" AND domain:au
+#       127 "Australian Eastern Daylight Time" AND domain:au
+#
+#   Here "Summer" seems quite a bit more popular than "Daylight",
+#   particularly when we know the time zone is Australian and not US,
+#   say.  The "Australian" prefix seems to be popular for Eastern Summer
+#   Time, but unpopular for Eastern Daylight Time.
+#
+#   For abbreviations, tools like AltaVista are less useful because of
+#   ambiguity.  Many hits are not really time zones, unfortunately, and
+#   many hits denote US time zones and not Australian ones.  But here
+#   are the hit counts anyway:
+#
+#     161,304 "EST" and domain:au
+#      25,156 "EDT" and domain:au
+#      18,263 "AEST" and domain:au
+#      10,416 "AEDT" and domain:au
+#
+#      14,538 "CST" and domain:au

+# discussing his book "The Sun in the Church: Cathedrals as Solar
+# Observatories"[1], and in particular the Shrine of Remembrance[2] located
+# in Melbourne, Australia.
+#
+# Apparently the shrine's main purpose is a beam of sunlight which
+# illuminates a special spot on the floor at the 11th hour of the 11th day
+# of the 11th month (Remembrance Day) every year in memory of Australia's
+# fallen WWI soldiers.  And if you go there on Nov. 11, at 11am local time,
+# you will indeed see the sunbeam illuminate the special spot at the
+# expected time.
+#
+# However, that is only because of some special mirror contraption that had
+# to be employed, since due to daylight savings time, the true solar time of
+# the remembrance moment occurs one hour later (or earlier?).  Perhaps
+# someone with more information on this jury-rig can tell us more.
