Java - always keep two decimal places even in zeroes
decimalformat, java
Solution
It is because you are using `Double.valueOf` on the `DecimalFormat` and it is converting the formatted number back to a double, therefore eliminating the trailing 0s.
To fix this, only use the `DecimalFormat` when you are displaying the value.
If you need `m_interest` calculations, keep it as a regular `double`.
Then when displaying, use:
System.out.print(df.format(m_interest));
Example:
DecimalFormat df = new DecimalFormat("#.00");
double m_interest = 1000;
System.out.print(df.format(m_interest)); // prints 1000.00
Problem
I am trying to keep two decimal places, even if then numbers are zeroes, using `DecimalFormatter`: ``` DecimalFormat df = new DecimalFormat("#.00"); m_interest = Double.valueOf(df.format(m_principal * m_interestRate)); m_newBalance = Double.valueOf(df.format(m_principal + m_interest - m_payment)); m_principal = Double.valueOf(df.format(m_newBalance)); ``` However for some values this gives two decimal places, and for others it doesnt. How can i fix this?
