@julianhyde The cause of the problem is that, minus operator '-' is not right for type BigDecimal when implementing unary minus function For example ``` int a = 1; int b = -a; ``` The above is Ok, however, problem exists in the code below ``` BigDecimal a = BigDecimal.valueOf(1); BigDecimal b = -a; //wrong BigDecimal c = a.nagate();//right ``` ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
