Expand description

Compares two iterators of “characters” possibly containing “digits”. The natural ordering can be customized with the following parameters:

  • skip returns true if the “character” does not affect the comparison, other than splitting two consecutive digits.
  • cmp compares two “characters”, assuming that they are not “digits”.
  • to_digit converts a “character” into a “digit” if possible. The digit of zero is special.
