Exception: If the specified scaling operation would require rounding then Arithmetic Exception is thrown. The java.math.BigDecimal.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. To specify the number of digits after the decimal point use BigDecimal.setScale(scale, mathContext). If zero or positive, the scale is the number of digits to the right of the decimal point. The specified rounding mode is applied to the division. Description. 1.2. dec. Kotlin for Data Science. Using big-math in your projects . setScale public BigDecimal setScale(int newScale, int 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. CodeMonk. mathContext - … ; For negative value, the unscaled value of the number is multiplied by ten to the power of the negation of the scale. The suggested idiom for performing these comparisons is: (x.compareTo(y) 0), where is one of the six comparison op… Kotlin for Native. setScale() It is used to set the new scale with the given scale of this BigDecimal object. Fun with Java’s floating-point arithmetics Those of you who learned Java in an academic context probably remember something fishy around FP arithmetics. » Subscribe through email. What's New in 1.3. Below programs is used to illustrate the setScale() method of BigDecimal. Kotlin provides several functions (in infix form) to perform bitwise and bitshift operation. These are non-static methods and it is accessible with class objects and if we try to access these methods with the class name then we will get an error. fun setScale (sx: Float, sy: Float) Contributing to Kotlin Releases Press Kit Security Blog Issue Tracker. 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. It is used to get the scale of this BigDecimal object. » HR » C++ こんにちは!フリーランスの長野です。 割り算を行う場合、計算結果の数値の小数点以下を四捨五入したり、切り上げ・切り捨てなどの端数処理をしたいことがありますよね。 そんな時にJavaではBigDecimalクラスを使用します。 この記事では、BigDecimalクラスについて BigDecimalクラ … What's New in 1.2.
