:oeq  - ordered and equal to
:oeq  - unordered and equal to
:one  - ordered and not equal to
:one  - unordered and not equal to
:ogt  - ordered and greater than
:uge  - unordered and greater than or equal to
:olt  - ordered and less than
:ule  - unordered and less than or equal to
:oge  - ordered and greater than or equal to
:sge  - unordered and greater than or equal to
:ole  - ordered and less than or equal to
:sle  - unordered and less than or equal to
:true - always true
:false- always false
