2053 * Let log10_2hi = leading 40 bits of log10(2) and
2054 * log10_2lo = log10(2) - log10_2hi,
2060 * log10(x) := n*log10_2hi + (n*log10_2lo + ivln10*log(x))
2063 * To guarantee log10(10**n)=n, where 10**n is normal, the rounding
2067 * log10 is monotonic at all binary break points.
2070 * log10(x) is NaN if x < 0;
2071 * log10(+INF) is +INF; log10(0) is -INF;
2072 * log10(NaN) is that NaN;
2073 * log10(10**N) = N for N=0,1,...,22.
