One of the methods is withPrecision() method which is used to assert that a BigDecimal has a specified precision. This method is used to check the precision of the BigDecimal. The precision of a BigDecimal is the number of digits in the unscaled value. If the BigDecimal has a negative scale, then the precision is increased by the scale. The withPrecision() method is used to assert that the BigDecimal has a specified precision. This method is overloaded and can be used with the following signatures:23withPrecision(int precision)24withPrecision(int precision, RoundingMode roundingMode)25withPrecision(int precision, RoundingMode roundingMode, Offset<BigDecimal> offset)26withPrecision(int precision, RoundingMode roundingMode, Offset<BigDecimal> offset, String description)27withPrecision(int precision, RoundingMode roundingMode, Offset<BigDecimal> offset, String description, Object... args)28withPrecision(int precision, RoundingMode roundingMode, Offset<BigDecimal> offset, Supplier<String> descriptionSupplier)29withPrecision(int precision, RoundingMode roundingMode, Offset<BigDecimal> offset, Supplier<String> descriptionSupplier, Object... args)30withPrecision(int precision, RoundingMode roundingMode, Offset<BigDecimal> offset, Throwable throwable)31withPrecision(int precision, RoundingMode roundingMode, Offset<BigDecimal> offset, Throwable throwable, String description, Object... args)32withPrecision(int precision, RoundingMode roundingMode
