Compute atan( num_d / den_d ) in double-double precision. num_d = min(|x|, |y|) den_d = max(|x|, |y|) q_d = num_d / den_d idx, k_d

Approximate atan(x) for |x| <= 2^-5. Using degree-3 Taylor polynomial: P = x - x^3/3 Then the absolute error is bounded by: |atan(x) - P(x)| < |x|^5/5

Evaluate atan without big lookup table. atan(n/d) - atan(k/16) = atan((n/d - k/16) / (1 + (n/d) * (k/16))) = atan((n - d * k/16)) / (d + n * k/16)) So

Can be called to attempt to increase or decrease the size of the given region to a new size (in-place). Returns 1 if resize succeeds, and 0 on failure

I'm not sure this should go in ctype_utils since the specific ordering of base64 is so very implementation specific, and also this set is unusual. Ret
