JavaScript dataView.setUint16() Method
The dataView.setUint16() is an inbuilt function in dataView that is used to store an unsigned 16-bit integer at the specified location i.e, at byte offset from the start of the dataView.
Syntax:
dataView.setUint16(byteOffset)
Parameters: It has the parameter byteOffset which is offset in a byte and it says from the start of the view where to read the data.
Return value: This function does not return anything.
Below are examples of the dataView.setUint16() Method.
Example 1:
javascript
var buffer = new ArrayBuffer(20);
var dataview1 = new DataView(buffer, 0, 10);
dataview1.setUint16(1, 12);
console.log(dataview1.getUint32(1));
|
Output:
12
Example 2:
javascript
var buffer = new ArrayBuffer(20);
var dataview1 = new DataView(buffer, 0, 10);
dataview1.setUint16(1, 56);
console.log(dataview1.getUint16(1));
|
Output:
56
Example 3:This function does not accept float value that is why it convert float value to integer value. It can be seen from the output of the below program it should give output as 3.14 (the value of PI) but this function convert this value to 3.
javascript
var buffer = new ArrayBuffer(20);
var dataview1 = new DataView(buffer, 0, 10);
dataview1.setUint16(1, Math.PI);
console.log(dataview1.getUint16(1));
|
Output:
3
Example 4: When there is no data to be stored, then it gives output as zero (0).
javascript
var buffer = new ArrayBuffer(20);
var dataview1 = new DataView(buffer, 0, 10);
dataview1.setUint16(1);
console.log(dataview1.getUint16(1));
|
Output:
0
