In another way, the constructor with adoublevalue, 147.87932 is converted to the closest double value 147.8793200000000069849193096160888671875. Hope you understand How the BigDecimal object is created in Java.
For example, we can convert a decimal-based long value without removing non-numeric symbols: BigDecimalbigDecimal=newBigDecimal(10692467440017.111).setScale(3, BigDecimal.ROUND_HALF_UP);DecimalFormatSymbolssymbols=newDecimalFormatSymbols(); symbols.setGroupingSeparator(','); symbols.setDecimalSeparator('.'...
java.mathBigDecimalvalueOf Javadoc Returns a new BigDecimal instance whose value is equal to val. The new decimal is constructed as if the BigDecimal(String)constructor is called with an argument which is equal to Double.toString(val). For example, valueOf("0.1") is converted to (unscaled=1...
It is used when the integers involved are larger than the limit of thelongtype.For example, the factorial of 50 is30414093201713378043612608166064768844377641568960512000000000000.This value is too big for anint or longdata type to handle. It can only be stored in aBigIntegervariable. It is widely ...
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...
