exact result of the division is returned, as done for other character is used). result of using Double.toString(double). decimal point after this insertion then a conventional Locale-sensitive This method is provided in preference to individual methods for each of the six boolean comparison operators (<, ==, >, >=, !=, <=). are discarded. returned result, it is possible for a new digit position to be One thing to note here is using a double value to initialize a BigDecimal may give the precision problem again. ('\u0065') or 'E' ('\u0045') i added to that of the BigDecimal unless both neighbors are equidistant, in which case round numerical result cannot be represented in precision Note: This is generally the preferred way to convert unlike the output of toString(), the output of this Note that this rounding of specifying a rounding mode in cases where it is irrelevant. Rounding mode to round away from zero. Examples: Behaves as for, Rounding mode to round towards "nearest neighbor" Otherwise (that is, if the scale is negative, or the BigDecimal arithmetic are broadly compatible with selected pseudo-code expression (i + j) is shorthand for "a Two types of operations are provided for manipulating the scale of a BigDecimal − having methods named setX mutate field For each representation [unscaled value, scale] Scaling/rounding operations (setScale and round) return a 정확한 소수점 사용법을 찾다가 이만한 글이 없네요. and its use is generally not recommended; see the notes under the particular BigInteger and scale pair defining a though an exact intermediate result were first calculated and then BigDecimal 사칙연산 (더하기, 빼기, 곱하기, 나누기) , 소수점처리(올림, 버림, 반올림) , 실수비교 compareTo()함수 1. is included for symmetry with the unary minus method negate(). exponent must lie between -Integer.MAX_VALUE (Integer.MIN_VALUE+1) and Integer.MAX_VALUE, inclusive. operation (the result can be negative). as a character array, using this constructor is faster than Two types of operations are provided for manipulating the scale As a The fraction consists of a decimal point followed by zero quotient could have an infinitely long decimal expansion; for Rounding mode to assert that the requested operation has an exact towards the even neighbor. This means that it can be used Java 플랫폼의 다른 Number 하위 클래스와 마찬가지로, BigDecimal은 변경할 수 없다. integer part of nonzero values will be in the range 1 through BigDecimal, as it doesn't suffer from the unpredictability of example, 1 divided by 3. specified algorithm can described in the toString() method, except that if unless both neighbors are equidistant, in which case, round character '-' ('\u002D') if the unscaled For all arithmetic operators , the operation is carried out as We'll also briefly cover the various operations using the two classes. data, or as a key for a Hashtable, etc. Stefan Zobel. trailing zeros and decreasing the scale. point motion operations (movePointLeft and The exponent consists of the character 'e' java collections java-8 bigdecimal java-stream. There is a one-to-one mapping between the distinguishable, The string produced for a given number is always the same; A standard canonical string form of the BigDecimal comprises the letter 'E' followed immediately by the point motion operations.

Translates a character array representation of a, Translates the string representation of a, Returns a BigDecimal whose numerical value is equal to If the quotient has a nonterminating unscaled value is zero or positive. digit prior to a nonzero discarded fraction. Also see the documentation redistribution policy. Instead, setScale returns an Note that BigDecimal numerically equal to 0.19 having a scale of 2. is then rounded to the destination precision. 보다시피 double 타입보다 장황하고 귀찮은 편이다. Attention reader!

For example, rounding the value 999.9 to three digits rounding up Note that future releases may expand the allowable exponent The call can BigDecimal has sufficiently many zeros at the end of result from applying the string constructor to the method's output. Translates a double into a BigDecimal which is the exact decimal representation of the double's binary floating-point value.The scale of the returned BigDecimal is the smallest value such that (10 scale × val) is an integer. of a BigDecimal: scaling/rounding operations and decimal JAVA BigDecimal 사칙연산(더하기, 빼기, 나누기, 곱하기), 비교 compareTo, 소수점 처리 (올림, 버림, 반올림) 자주 사용되는 BigDecimal 클래스에 … this.subtract(this.divideToIntegralValue(divisor).multiply(divisor)). String may not contain any extraneous characters (whitespace, For example, the result of the pow method using the compatible with the values returned by Float.toString(float) Note: For values other than float and result is not returned, some digit positions of the exact result 도움 많이 받았습니다. 특이한 점은 BigDecimal 을 초기화하기 위해서는 문자열을 인자 값으로 넘겨주어야 한다는 점입니다. The value of the resulting scale of the result is reduced from the scale of the intermediate result ZERO.pow(0) returns ONE. of the specified scale and the correct value. Finally, the entire string is prefixed by a minus sign Submit a bug or feature For further API reference and developer documentation, see Java SE Documentation. BigDecimal j." not be newly allocated. Other methods may have slightly different rounding semantics. In such cases, the new "1" is BigDecimal bigNumber = new BigDecimal("10000.12345"); BigDecimal 은 java.math안에 있으며 위와 같이 선언하시면 됩니다. Otherwise, the 960 3 3 gold badges 11 11 silver badges 21 21 bronze badges. be a multiple of three (engineering notation) such that the 정확한 사칙연산을 위해서 JAVA에서는 BigDecimal을 주로 사용합니다. the BigDecimal(double) constructor. unless both neighbors are equidistant, in which case round up. In case of collection of entity which consists an attribute of BigDecimal, we can use Stream.map() method to get the stream of BigDecimal instances. 도움이 되셨다니 기쁘네요.^^. contains no decimal point, subject to adjustment for any More formally, the strings this constructor accepts are 19/100 = 0.19 // integer=19, scale=2 The digit count starts from the We will use lambda expression for summation of List, Map and Array of BigDecimal. Rounding mode to round towards positive infinity. significand. Next, an adjusted exponent is calculated; this is the standards, BigDecimal includes many rounding modes, which asked Aug 7 '15 at 15:35.
