307 * exp2(x): compute the base 2 exponential of x
315 * Thus we have exp2(x) = 2**k * exp2(y).
319 * Thus we have exp2(y) = exp2(i/TBLSIZE) * exp2(z - eps[i]),
322 * We compute exp2(i/TBLSIZE) via table lookup and exp2(z - eps[i]) via
325 * exp2t[i] = exp2(i/TBLSIZE + eps[i]), and eps[i] is a small offset such
338 exp2(double x)
372 /* Compute r = exp2(y) = exp2t[i0] * p(z - eps[i]). */
