After 24 years of greglove@oz.net as my
primary email -- my only personal email before that was with Compuserve -- I'm
finally joining the modern world and transitioning to gmail. My new email is
greg.j.lovern@gmail.com. This
should cut down on my emails going to your spam folder.

xlPrecision 2018 is released.
September 8, 2017:
xlPrecision 3.1.7 and 2017b are released. These versions fix bugs in xlpCOS and
xlpACOS. When the input for xlpCOS was 0, or so close to 0 that for the maximum
significant digits in effect it would return the same result as 0, xlpCOS
returned 0 instead of 1. When the input for xlpACOS was within 0.000000000000001
of 0, 1, or -1, xlpACOS returned pi/2, 0, or pi respectively, as if the input
was exactly 0, 1, or -1.
November 5, 2016:
xlPrecision 2017 is released. Read about the
new features in xlPrecision 2017
here.
The Free Edition has not yet been updated to 2017. Until then, unless xlPrecision 2017 is specifically requested, xlPrecision 3.1.6 will still be sent to customers who buy xlPrecision. This is in order to avoid requiring an additional manual step during installation (xlPrecision 2017 requires a new xlPrecision.xla file). Once the Free Edition has been upgraded to xlPrecision 2017, paying customers will get xlPrecision 2017 automatically.
