source: trunk/yat/utility/DataWeight.cc @ 1734

Last change on this file since 1734 was 1734, checked in by Peter, 13 years ago

Added some docs. Also modified the comparison operators to return what
the corresponding double operator returns for data(). This was always
true before when the comparisons included NaN.

  • Property svn:eol-style set to native
