Round number to only first decimal place

I would like to know the available phone memory, so I wrote this code.

File path2 = Environment.getDataDirectory();
StatFs stat2 = new StatFs(path.getPath());
lo         


        

Answer 1

Have you tried using free = Math.round(free * 10) / 10d; instead of free = Math.round(size * 10) / 10d;? I don't see size as a defined variable.

A simple test of

double free = 5.654707363;
free = Math.round(free * 10) / 10d;
System.out.println(free);

outputs 5.7.
