What is BigDecimal value in java?
A BigDecimal consists of an arbitrary precision integer unscaled value and a 32-bit integer scale. If zero or positive, the scale is the number of digits to the right of the decimal point. If negative, the unscaled value of the number is multiplied by ten to the power of the negation of the scale.
What is default value for BigDecimal in java?
null
If you are using type BigDecimal, then its default value is null (it is object, not primitive type), so you get [1] automatically.
How do you assign a value to big decimal?
The best way to create a BigDecimal object with an initial decimal value is via a string, like this: BigDecimal value = new BigDecimal(“0.01”); Here, value has a value of exactly 0.01. If the initial value is an integer, you can safely pass it to the constructor.
What does 0E 8 mean?
0E-8 is a translation of 0 with 8 decimal places. I assume you’re getting this by calling toString() on a decimal. If you would be comparing the actual decimal attribute to your value the result should correctly indicate your decimal is 0.
What is RoundingMode in BigDecimal java?
setScale(int newScale, RoundingMode roundingMode) returns a BigDecimal whose scale is the specified value, and whose unscaled value is determined by multiplying or dividing this BigDecimal’s unscaled value by the appropriate power of ten to maintain its overall value.
How do you use setScale in java?
setScale(int newScale, int roundingMode) This method is used to calculate a BigDecimal whose scale is the specified value, and whose unscaled value is determined by multiplying or dividing this BigDecimal’s unscaled value by the appropriate power of ten to maintain its overall value.
How do you convert Longinteger to Longinteger?
BigInteger. valueOf(long val) returns a BigInteger whose value is equal to that of the specified long. This “static factory method” is provided in preference to a (long) constructor because it allows for reuse of frequently used BigIntegers.
