Scroll down to getOvers method, You can find it by reading comments, that comment starts with convert.

Here, I returned overs variable, type : double. It sometimes returns 1.2 etc , which is correct, but sometimes it returns 0.300000004 etc, which I need to get truncated. Thanks..

Answer 1

I inspected your code
do it through double casting
return overs = (double) ((int) (overs*10))/10;

Answer 2

Try to use BigDecimal wrapper instead double.
To determine the number of digits, there is a method:
int scale().
To specify the requared number of digits:
setScale(int, roundingMode)
Note that BigDecimal objects are immutable.
