Description

Currently errol3 is used:

  • Errol is fast and correct
  • The paper on it is unclear and I'm not sure, whether the implemention is correct
  • Described only for double

Ryu (https://dl.acm.org/ft_gateway.cfm?id=3192369&type=pdf):

  • At a first glance the algorithm is simpler (or the description is better)
  • Is faster and still correct
  • Described for float and double
  • Not that good for real since it would require too big lookup tables
