310  * exp2(x): compute the base 2 exponential of x
318  *     Thus we have exp2(x) = 2**k * exp2(y).
322  *     Thus we have exp2(y) = exp2(i/TBLSIZE) * exp2(z - eps[i]),
325  *   We compute exp2(i/TBLSIZE) via table lookup and exp2(z - eps[i]) via
328  *   exp2t[i] = exp2(i/TBLSIZE + eps[i]), and eps[i] is a small offset such
