While looking through ES3 for other things, I happened to notice a minor fault. What is the best way to record it so it can be fixed in due course?
The error is in an informative note, so is not critical. It is in section 15.8.2.15, NOTE 2, which states: "The value of Math.round(x) is the same as the value of Math.floor(x+0.5), except when x is ?0 or is less than 0 but greater than or equal to -0.5; for these cases math.round(x) returns ?0, but Math.floor(x+0.5) returns +0." This is not true when x is 0.49999999999999994, which when converted to double is the next representable value below 0.5. In this case, Math.floor(x+0.5) would return +1 but Math.round(x) would return +0.
