Enum Constant Detail

ROUND_DOWN

public static final DfpField.RoundingMode ROUND_DOWN

Rounds toward zero (truncation).

ROUND_UP

public static final DfpField.RoundingMode ROUND_UP

Rounds away from zero if discarded digit is non-zero.

ROUND_HALF_UP

public static final DfpField.RoundingMode ROUND_HALF_UP

Rounds towards nearest unless both are equidistant in which case it rounds away from zero.

ROUND_HALF_DOWN

public static final DfpField.RoundingMode ROUND_HALF_DOWN

Rounds towards nearest unless both are equidistant in which case it rounds toward zero.

ROUND_HALF_EVEN

public static final DfpField.RoundingMode ROUND_HALF_EVEN

Rounds towards nearest unless both are equidistant in which case it rounds toward the even neighbor. This is the default as specified by IEEE 854-1987

ROUND_HALF_ODD

public static final DfpField.RoundingMode ROUND_HALF_ODD

Rounds towards nearest unless both are equidistant in which case it rounds toward the odd neighbor.

ROUND_CEIL

Rounds towards positive infinity.

ROUND_FLOOR

public static final DfpField.RoundingMode ROUND_FLOOR

Rounds towards negative infinity.

Method Detail

values

public static DfpField.RoundingMode[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (DfpField.RoundingMode c : DfpField.RoundingMode.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static DfpField.RoundingMode valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
