Also, how is BigDecimal defined?
A BigDecimal consists of a random precision integer unscaled value and a 32-bit integer scale. If greater than or equal to zero, the scale is the number of digits to the right of the decimal point. If less than zero, the unscaled value of the number is multiplied by 10^(-scale).
Additionally, what is scale and precision in BigDecimal? Java BigDecimal Precision and Scale By Definition, precision indicates the length of arbitrary precision integer whereas scale means the number of digits to the right of the decimal point. For example if we have a number “100.25” then precision is 5 because we need five digits to write down this number and scale is 2.
People also ask, what is the use of BigDecimal in Java?
The BigDecimal class provides operation for arithmetic, comparison, hashing, rounding, manipulation and format conversion. This method can handle very small and very big floating point numbers with great precision. In java, BigDecimal consists of a random precision integer scale and a 32-bit integer scale.
What is the base of BigDecimal data type?
Explanation: A BigDecimal is n*10^scale where n is an arbitrary large signed integer. Scale can be thought of as the number of digits to move the decimal point to left or right.
