CalculationPrecisionStrategy enumeration

CalculationPrecisionStrategy enumeration

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.

The CalculationPrecisionStrategy type exposes the following members:

Fields

FieldDescription
NONENo 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.
ROUNDRounds the calculation result according with significant digits.
DECIMALUses decimal as operands when possible.
Most inefficient for performance.
