Android java code to remove recurring zeros from 3rd place after decimal point

Following is the Java code to check if the number is whole number or decimal number and display the result accordingly:

if (result % 1 == 0) {
    String finalResultString = String.format("%.0f", result); 
} else {
    BigDecimal decimalResult = new BigDecimal(result);
    String resultString = String.format("%.15f", decimalResult);
}

But in the decimal part:

1) If I run 66%6, I get 3.960000000000000 but I want the answer to be 3.96 only. So I do not want the unnecessary zeros to be displayed.

2) If I run 99 x 65.00055, I want the answer to be 15 digits in after decimal place like 6435.054450000000543

So the thing is - I don't want zeros depending on the leading digit. Like if the result is 5.645345600000000 or 3.960000000000000, I want the result to be either 5.6453456 or 3.96. If the result is 6435.054450000000540, I want 14 digits of precision in the result to be shown since i don't want the last unnecessary zero to be shown. If the result is 6435.000000000000003, I want all the 15 digits of precision to be shown since there are no unnecessary zeros at the end

Can anyone please help?

Thanks in advance

You can set the decimal scale to 2:

decimalResult = decimalResult.setScale(2);
