You could use the string formatting operator for that:
>>> '%.2f' % 1.234
'1.23'

E.g.:
%f = 25.000000
%.f = 25
%.02f = 25.00

How can I format a decimal to always show 2 decimal places?

String.format() to format double in java
...
String.format("%1$,.2f", myDouble);
String.format automatically uses the default locale.
