//       The ceil function doesn't work when rowLengths and the other this.->... is 

//       typecasted into ( RealType ), because when RealType is int, it will perform 

//       an integer division and return the int as a double, which in this case 

//       will be zero and make the assertion fail ( https://stackoverflow.com/questions/33273359/in-c-using-the-ceil-a-division-is-not-working ).

//       To fix this, typecast them to ( float ), instead of ( RealType )

                          roundUpDivision( rowLengths[ i ], this->rowToChunkMapping[ i ] ) );
