Enumerates strategies for handling calculation precision. Because of the precision issue of IEEE 754 Floating-Point Arithmetic, some “seemingly simple” formulas may not be calculated as the expected result. Such as formula “=-0.45+0.43+0.02”, when calculating operands by ‘+’ operator directly, the result is not zero. For such kind of precision issue, some special strategies may give the expected result.
public enum CalculationPrecisionStrategy
|None||No strategy applied on calculation. When calculating just use the original double value as operand and return the result directly. Most efficient for performance and applicable for most cases.|
|Round||Rounds the calculation result according with significant digits.|
|Decimal||Uses decimal as operands when possible. Most inefficient for performance.|
