# Thread: float to 2 decimal places

1. ## float to 2 decimal places

hello to all,
is there any easy way to convert a float to 2 decimal places?
all the examples on the net are too complicated

`	f = f/99;`

this is all i want to do.

thank you!

2. ## Re: float to 2 decimal places

If you can guarantee that your number can fit inside an int (or a long), do this:

```long temp = 100.0 * f;
f = temp/100.0;```

Or, in one line:

`f = ((long)(100.0*f))/100.0;`

edit: as a side question, why do you want to only have 2 decimal precision? It's generally advisable to have all the decimals in place, and then only display out to two decimals precision.

`System.out.printf("f is %f, which is %.2f with 2 decimals precision",f,f);`

well this is the actual code:
```
double meanValue = 0;
meanValue = meanValue + rndNumber;
double mean = meanValue / 99;
System.out.println("The Mean Value is :" + mean);```

the result appears as : 1.5555555555555556

is there any way to reduce to 2 decimal points?

the one above didn't really help!

thank you!

4. ## Re: float to 2 decimal places

The thing is that float and double will never really only be two decimals, it all depends on the precision of the operating system.

However if you wish to print the float/double value with only two decimals then you can use the method a couple of posts above.

`System.out.printf("The Mean Value is : %.2f", mean);`

Have a look at Formatter (Java Platform SE 6) for more information on how to print using formatter.
