question: private static int uarimaxLt ( double value , double [ ] bv , int [ ] bvi , BinaryOperator bOp ) throws DMLRuntimeException { int ixMax = bv . length ; if ( value < bv [ 0 ] || value >= bv [ bv . length - 1 ] ) return ixMax ; int ix = Arrays . binarySearch ( bv , value ) ; if ( ix < 0 ) ix = Math . abs ( ix ) - 2 ; ixMax = bvi [ ix ] + 1 ; return ixMax ; }
target:  Find out rowIndexMax for LessThan operator.
