Subject [GitHub] metron issue #681: METRON-1079 Add NaN as a keyword in STELLAR language
Date Tue, 15 Aug 2017 17:11:47 GMT
Github user mattf-horton commented on the issue:
    Technically this is correct, as for example SQRT(-1) and SQRT(-2) clearly should not show
as equal, but by using NaN we (deliberately) lose the info that would allow us to recognize
that SQRT(-1)==SQRT(-1).
    To detect/validate NaN, we would need an operator IS_NAN(x).
