13 /* log10(x)
17 * Let log10_2hi = leading 40 bits of log10(2) and
18 * log10_2lo = log10(2) - log10_2hi,
24 * log10(x) := n*log10_2hi + (n*log10_2lo + ivln10*log(x))
27 * To guarantee log10(10**n)=n, where 10**n is normal, the rounding
31 * log10 is monotonic at all binary break points.
34 * log10(x) is NaN with signal if x < 0;
35 * log10(+INF) is +INF with no signal; log10(0) is -INF with signal;
36 * log10(NaN) is that NaN with no signal;
37 * log10(10**N) = N for N=0,1,...,22.
