Maybe the 'problem' is not in the ROUND() function but the CAST() ?

For exact numbers you have to use exact numeric types.
Double is float point type with all advantages and disadvantages.
Look here

Just for fun, try this:
1e20 + 1 + 1 - 1e20 + 1

In binary representation of the values maybe 4.72 is the closest, but we are
talking about mathematic.
This is from the description of the ROUND function in the documentation:
Rounds a number to the nearest integer. If the fractional part is exactly 0.5,
rounding is upward for positive
