NB - you get the same result in MS-SQL (and for exactly the same reason). Ruby behaves like SQL in that appending a decimal to the values results in non-integer maths being employed. MS-SQL itself is slightly out (I assume due to floating point inaccuracy) SELECT (289.0 / 30.0 * 30.0) - (149.0 / 30.0 * 30.0)
