Properties

Category	Property	Description
Precision	Specify precision	Select whether to directly specify the decimal places of precision in decimal type calculation.
Precision	Specified digits	Directly specify the number of decimal places in decimal type precision.
Precision	Rounding	Specify the method of rounding.
Null processing	Null option	Specify how to handle the input if it contains null.
Comment	Comment	You can write a description of the logic. It doesn't affect the conversion process.

Null option

Option	Description

Specification limits

An exception (CalculationException) is thrown when a value smaller than "0" is specified to input data.

Notes

If Specified digits is not selected, the result is output in fractional value.
- For example, if "4" is entered, the result is "2.0".
An approximate value is adopted as a result if the value cannot be precisely indicated with 64-byte floating point like the square root of 10.
