Today, when debugging a java program, the following exception error message appears:

java.lang.ArithmeticException: Non-terminating decimal expansion; no exact representable decimal result。

The error statements are as follows:

If you use BigDecimal to do Division in Java, you must pass the second parameter in the divide method, and the definition must be accurate to a few decimal places. Otherwise, if the result is infinite circular decimal without integer division, the above exception will be thrown
solutions

Note that there are two overloaded methods for this divide method. One is to pass two parameters, and the other is to pass three parameters

Two parameter method:

@Param divisor value by which this {@ code BigDecimal} is to be divided

@Param rounding mode rounding mode to apply

The method of three parameters is as follows

@Param divisor value by which this {@ code BigDecimal} is to be divided. Incoming divisor
@ param scale of the {@ code BigDecimal} quotient to be returned
