JavaScript DataView.getInt16() method

The JavaScript DataView.getInt16() is an inbuilt method in dataView. It is used to get a signed 16-bit integer(short) number at a specified location.

NOTE: Range of 16-bit integer value is from 0 and 65,535 for unsigned and from ?32,768 to 32,767 for signed integer value.

Syntax

Parameters

byteoffset: The offset, in a byte, from the start of the view where to read the data.

Example 1

<script>
//JavaScript to illustrate dataview.getInt16() method
// creating a ArrayBuffer 
var JavaTpoint = new ArrayBuffer(8);
// creating a view
var arr = new DataView(JavaTpoint);
// put the value 3.1 at slot 1
document.write("If we give a float value then output will be an Integer<br><br>");
arr.setInt16(1,3.1);
document.write(arr.getInt16(1));
//expected output:3
</script>

Test it Now

Output:

If we give a float value then output will be an Integer

3

Example 2

<script>
//JavaScript to illustrate dataview.getInt16() method
// if there is no data to be stored then it returns Nan
// creating a ArrayBuffer 
var JavaTpoint = new ArrayBuffer(8);
// creating a view
var arr = new DataView(JavaTpoint);
// NO Data
arr.getInt16(1);
document.write(" If  there is no data to be stored, then Output will Be:<br><br>")
document.write(arr.getInt16(1));
//expected output:0
</script>

Test it Now

Output:

If there is no data to be stored, then Output will Be:

0

Example 3

<script>
//JavaScript to illustrate dataview.getInt16() method
// creating a ArrayBuffer 
var JavaTpoint = new ArrayBuffer(8);
// creating a view
var arr = new DataView(JavaTpoint);
//We can also use math function like Math.PI
document.write("PI value will be <br><br>");
arr.setInt16(1,Math.PI);
document.write(arr.getInt16(1));
//expected output: 3
</script>

Test it Now

Output:

PI value will be

Example 4

<script>
//JavaScript to illustrate dataview.getInt16() method
// creating a ArrayBuffer 
var JavaTpoint = new ArrayBuffer(8);
// creating a view
var arr = new DataView(JavaTpoint);
// put the value 7 at slot 1
arr.setInt16(1,7);
document.write("If we provide Integer value then output will be<br><br>")
document.write(arr.getInt16(1));
//expected output: 7
</script>

Test it Now

Output:

If we provide Integer value then output will be.
