    Re: Constructing A Logarithm Table
    From: Hewitt Schlereth
    Date: 2009 Jan 13, 23:28 -0400

    Anon's 11.493 could well be closer than my 11.5. I worked with my
    HP35s calculator and the x^y function key and only checked 30�, 25�,
    06', 16', and 45�.  So, for instance, I got Pepperday's Log of 28.385
    as 11.5 to the -.28385 power times -100 which shifts the decimal and
    cancels the minus sign.
