ByteRounding class abstract

Extended rounding strategies for byte value formatting.

Provides additional rounding methods beyond the standard round, floor, and ceil operations, including banker's rounding and various tie-breaking strategies.

Example:

final value = 1.5;
print(ByteRounding.round(value, precision: 0));      // 2.0
print(ByteRounding.floor(value, precision: 0));      // 1.0
print(ByteRounding.ceil(value, precision: 0));       // 2.0
print(ByteRounding.truncate(value, precision: 0));   // 1.0
print(ByteRounding.halfUp(value, precision: 0));     // 2.0
print(ByteRounding.halfEven(value, precision: 0));   // 2.0 (banker's)

Static Methods

ceil(double value, {int precision = 2}) → double

Rounds toward positive infinity.

floor(double value, {int precision = 2}) → double

Rounds toward negative infinity.

halfAwayFromZero(double value, {int precision = 2}) → double

Rounds halves away from zero.

halfDown(double value, {int precision = 2}) → double

Rounds halves down (toward negative infinity).

halfEven(double value, {int precision = 2}) → double

Banker's rounding (rounds halves to nearest even).

halfTowardZero(double value, {int precision = 2}) → double

Rounds halves toward zero.

halfUp(double value, {int precision = 2}) → double

Rounds halves up (toward positive infinity).

round(double value, {int precision = 2}) → double

Standard rounding (rounds halves away from zero).

truncate(double value, {int precision = 2}) → double

Rounds toward zero (truncation).

withMode(double value, {int precision = 2, ByteRoundingMode mode = ByteRoundingMode.round}) → double

Rounds using the specified RoundingMode.
