BigDecimal removes extra 0 at the end

• If your data is 9.90, To become 9.9

new BigDecimal(“9.90”).stripTrailingZeros();

• 9.00 change 9

new BigDecimal(“9.00”).stripTrailingZeros();

At this time, the calculation result will become 4E+1 Or other values

• therefore , The final formulation should be

new BigDecimal(“9.00”).stripTrailingZeros().toPlainString();
