Square brackets are used to represent the particular BigInteger and scale pair defining a BigDecimal value; for example [19, 2] is the BigDecimal numerically equal to 0.19 having a scale of 2. Note: care should be exercised if BigDecimal objects are used as keys in a SortedMap or elements...
Return value: The return type of this method islong, it gets the long representation of this BigDecimal. Example: // Java program to demonstrate the example// of long longValue() method of BigDecimalimportjava.math.*;publicclassLongValueOfBD{publicstaticvoidmain(Stringargs[]){// Initialize tw...
Java在java.math包中提供的API类BigDecimal,用来对超过16位有效位的数进行精确的运算。 双精度浮点型变量double可以处理16位有效数,但在实际应用中,可能需要对更大或者更小的数进行运算和处理。一般情况下,对于那些不需要准确计算精度的数字,我们可以直接使用Float和Double处理,但是Double.valueOf(String) 和Float.value...
In the second case, it returns the converted long value to a BigDecimal. In the third case, it returns the BigDecimal and its value is calculated by using [(unsc_val) * 10 pow (-sc)]. Example: // Java program to demonstrate the example// of valueOf() method of BigDecimalimportjava...
