Using school half-up rounding, select all values that round to 5.2 to one decimal place.

Explication

The values 5.15 and 5.24 both round to 5.2: the former rounds its tenths up from a following 5, while the latter keeps it because the next digit is 4. The value 5.14 rounds to 5.1, and 5.25 rounds to 5.3, so endpoint rules exclude them.
