The result column in the tables could be gotten by creating a BigDecimal number with the specified value, forming a MathContext object with the proper settings (precision set to 1, and the roundingMode set to the rounding mode in question), and calling round on this number with the proper MathContext. We also set the rounding mode to Ceiling, this causes the last given place to be rounded to its next number. For example, when x = 5.60f, the output should be 6 and for x = -5.60f, the output should be -6.. 1.
