+ Here are the details:
+ Let k be the minimum length of the significand of x, and x' the odd
+ (integer) significand of x. This means that 2^(k-1) <= x' < 2^k.
+ Thus 2^(n*(k-1)) <= (x')^n < 2^(k*n), and x^n has between n*(k-1)+1
+ and k*n bits. So x^n can fit into p bits only if p >= n*(k-1)+1,

+ Note that x >= 2^k, so that x^n >= 2^(k*n). Since raw overflow
