How do you do BigDecimal division?

divide(BigDecimal divisor, int scale, RoundingMode roundingMode) returns a BigDecimal whose value is (this / divisor), and whose scale is as specified. If rounding must be performed to generate a result with the specified scale, the specified rounding mode is applied.

What is scale in BigDecimal divide?

Scale() of Divide method in BigDecimal Returns a BigDecimal whose value is (this / divisor), and whose preferred scale is (this. scale() – divisor. scale()); So in this case, 37146555.53880000’s scale is 8 , and 1000000 ‘s scale is 0 . So the result should have a scale of 8 , not 10 .

What is the difference between decimal and BigDecimal?

Java’s BigDecimal has the additional advantage that it can have an arbitrary (but finite) number of digits on both sides of the decimal point, limited only by the available memory. BigDecimal is Oracle’s arbitrary-precision numerical library.

What is BigDecimal scale?

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.

How do you sum BigDecimal?

math. BigDecimal. add(BigDecimal val) is used to calculate the Arithmetic sum of two BigDecimals. This method is used to find arithmetic addition of large numbers of range much greater than the range of largest data type double of Java without compromising with the precision of the result.

How do I set big decimal value?

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.

How do I know if my BigInteger is zero?

The java. math. BigInteger. signum() method helps us to identify whether a BigInteger is positive or zero or negative.

returns -1 when number is negative.
returns 0 when number is zero.
returns +1 when number is positive.

How to divide and divide a BigDecimal in Java?

Java.math.BigDecimal.divide() Method. Description. The java.math.BigDecimal.divide(BigDecimal divisor, int scale, RoundingMode roundingMode) returns a BigDecimal whose value is (this / divisor), and whose scale is as specified. If rounding must be performed to generate a result with the specified scale, the specified rounding mode is applied.

How do you calculate the remainder of a BigDecimal?

THis method returns a two-element BigDecimal array containing the result of divideToIntegralValue followed by the result of remainder on the two operands calculated with rounding according to the MathContext settings. This method returns a BigDecimal whose value is the integer part of the quotient (this / divisor) rounded down.

What is the return value of the BigDecimal method?

Return value: This method returns a BigDecimal which holds the result (this / divisor). Exception: If parameter divisor is 0 or the exact quotient does not have a terminating decimal expansion then Arithmetic Exception is thrown. Below programs is used to illustrate the divide () method of BigDecimal.

How is a double converted to a BigDecimal?

BigDecimal(double val) converts a double into a BigDecimal which is the exact decimal representation of the double’s binary floating-point value. BigDecimal(double val, MathContext mc) converts a double into a BigDecimal, with rounding according to the context settings.

How do you do BigDecimal division? divide(BigDecimal divisor, int scale, RoundingMode roundingMode) returns a BigDecimal whose value is (this / divisor), and whose scale is as specified. If rounding must be performed to generate a result with the specified scale, the specified rounding mode is applied. What is scale in BigDecimal divide? Scale() of Divide…
