/* Input: an approximation r*2^f to a real Y, with |r*2^f - Y| <= 2^(e+f).

   If rounding is possible, returns:
   - in s: a string representing the significand corresponding to
     the integer nearest to Y, within the direction rnd;
   - in exp: the exponent.

   n is the number of limbs of r.
   e represents the maximal error in the approximation to Y (see above),
      (e < 0 means that the approximation is known to be exact, i.e.,
      r*2^f = Y).
   b is the wanted base (2 <= b <= 62 or -36 <= b <= -2).
   m is the number of wanted digits in the significand.
   rnd is the rounding mode.
   It is assumed that b^(m-1) <= Y < b^(m+1), thus the returned value
   satisfies b^(m-1) <= rnd(Y) < b^(m+1).

   Rounding may fail for two reasons:
   - the error is too large to determine the integer N nearest to Y
   - either the number of digits of N in base b is too large (m+1),
     N=2*N1+(b/2) and the rounding mode is to nearest. This can
     only happen when b is even.

   Return value:
   - the direction of rounding (-1, 0, 1) if rounding is possible
   - -MPFR_ROUND_FAILED if rounding not possible because m+1 digits
   - MPFR_ROUND_FAILED otherwise (too large error)
