FixedLnOfOnePlus(System.Int32)

Method (no overloads)

Summary

ln(1 + j/64) in fixed point, for sixtyFourths = j
from -19 to 27, which covers [1/sqrt 2, sqrt 2]: the logarithm's
argument is divided by the nearest of these before its series, so that the
series' argument is within 1/256. Built outward from ln 1 = 0 when first
asked, one short series a step -- ln((64 + j)/(63 + j)) = 2 artanh(1/(127 + 2j)) above one and ln((64 - k)/(65 - k)) = -2 artanh(1/(129 - 2k)) below it.
