To avoid the outcome being lost, we have assigned it to another variableb3. Please refer theJavaDocin case you wish to explore it further. BigDecimal: java.math.BigDecimalclass is also an immutable classused to store and work with very large decimal numbers, the ones which can’t fit in b...
Java BigDecimal Class - Learn about the Java BigDecimal class, its methods and how to use it for precise calculations in Java programming.
TheBigDecimalclass gives its user complete control over rounding behavior. If no rounding mode is specified and the exact result cannot be represented, an exception is thrown. Main.java import java.math.BigDecimal; import java.math.RoundingMode; void main() { var x = new BigDecimal("5.54"); ...
Java BigDecimal Class Using BigDecimal to perform precise calculations with floats. BigDecimal is a class type. So declare/construct one BigDecimal is in the form like: 1BigDecimal pi =newBigDecimal("3.14159265358979323846");2BigDecimal pi =newBigDecimal(3.14);3BigDecimal pi =newBigDecimal(3.14f);4...

在使用BigDecimal进行相减操作时,可能会遇到以下异常:java.lang.ArithmeticException: Non-terminating decimal expansion; no exact representable decimal result.这个异常的出现是因为在进行减法运算时,结果会产生一个无穷尽的小数,而BigDecimal类的精度是有限的。
