Convert from Float to integer

Question

I built a simple Android "accelerometer" Sensor Application.

This is The Java Code link .

The output is like this:

X:8.87654322 Y:0.564321 Z:4.0195783

And sometimes it goes longer ...

I want to convert the float to an integer or just have 2 numbers

(I'm a beginner In Java.)
Thanks

Answer 1

double y = 9.37923929732232;
int a = (int)y;

Answer 2

double d = 4.232
int answer = (int) Math.round(d);

Answer 3

i think you want to convert float array values of accelerometer to int below is the float array with two float values i am just rounding off the value of float element of oth index using Math.round(arrayname[indexnumber])

float[] fArray = new float[] {(float) 6574.748, (float) 789.999};

    int f1 = Math.round(fArray[0]);
    System.out.println(f1);

this will round off the float value for ex 6574.748 will be rounded to 6575

Answer 4

To convert float sensor data to integer you have to mutiply them, and then round.

eg you want 1 digit after comma. 0.56432 -> 6

double y = 0.564321;
int yi = (int) Math.Round(y * 10); // for taking 2 digits after comma use 100

Then you have handy acceleration sensor data.

Answer 5

For getting two decimal places use ( java.text.DecimalFormat: )

You can try this

 double roundTwoDecimals(double d) { 
    DecimalFormat twoDForm = new DecimalFormat("#.##"); 
    return Double.valueOf(twoDForm.format(d));
 }  

For integer there are other answers in the post.
