How to remove the " .0" in a whole number when using double in java? [duplicate]
(3 answers)
Closed 4 years ago.
So, I have two numbers as strings - for example, 123.00 and 123.50. How do I remove the decimal point and all that follows. I had a method that worked for the 123.00, but would not work correctly on the 123.50.
Here is what I have so far:
String balance = getString("balance");
BigDecimal number = new BigDecimal(balance);
String formattedBalance = number.stripTrailingZeros().toPlainString();
int roundedBalance = Integer.parseInt(formattedBalance);
int roundedBalance = Integer.parseInt(getString("balance").split(".")[0]);
Do you want to remove the following points or numbers?
If only the points why not:
balance = balance.replace(".","");
