-+ * Return the logarithm to base 2 of x
-+ *
-+ * Method :
-+ * 1. Argument Reduction: find k and f such that
-+ * x = 2^k * (1+f),
-+ * where sqrt(2)/2 < 1+f < sqrt(2) .
-+ *
-+ * 2. Approximation of log(1+f).
-+ * Let s = f/(2+f) ; based on log(1+f) = log(1+s) - log(1-s)
-+ * = 2s + 2/3 s**3 + 2/5 s**5 + .....,
-+ * = 2s + s*R
-+ * We use a special Reme algorithm on [0,0.1716] to generate
-+ * a polynomial of degree 14 to approximate R The maximum error
-+ * of this polynomial approximation is bounded by 2**-58.45. In
-+ * other words,
-+ * 2 4 6 8 10 12 14
-+ * R(z) ~ Lg1*s +Lg2*s +Lg3*s +Lg4*s +Lg5*s +Lg6*s +Lg7*s
-+ * (the values of Lg1 to Lg7 are listed in the program)
-+ * and
-+ * | 2 14 | -58.45
-+ * | Lg1*s +...+Lg7*s - R(z) | <= 2
-+ * | |
-+ * Note that 2s = f - s*f = f - hfsq + s*hfsq, where hfsq = f*f/2.
-+ * In order to guarantee error in log below 1ulp, we compute log
-+ * by
-+ * log(1+f) = f - s*(f - R) (if f is not too large)
-+ * log(1+f) = f - (hfsq - s*(hfsq+R)). (better accuracy)
-+ *
-+ * 3. Finally, log(x) = k + log(1+f).
-+ * = k+(f-(hfsq-(s*(hfsq+R))))
-+ *
-+ * Special cases:
-+ * log2(x) is NaN with signal if x < 0 (including -INF) ;
-+ * log2(+INF) is +INF; log(0) is -INF with signal;
-+ * log2(NaN) is that NaN with no signal.
-+ *
-+ * Constants:
-+ * The hexadecimal values are the intended ones for the following
-+ * constants. The decimal values may be used, provided that the
-+ * compiler will convert from decimal to binary accurately enough
-+ * to produce the hexadecimal values shown.
