The dataView.setUint32() is an inbuilt function in dataView which is used to store an unsigned 32-bit integer at the specified location i.e, at byte offset from the start of the dataView.
Syntax:
dataView.setUint32(byteOffset,ValueToStoreAsUint32)
Parameters: byteOffset is the offset from the start of the data view.
Return value: This function does not return anything.
Below are examples of the dataView.setUint32() Method.
Example 1:
javascript
var buffer = new ArrayBuffer(20);var dataview1 = new DataView(buffer, 0, 10);dataview1.setUint32(1, 12);console.log(dataview1.getUint32(1)); |
Output:
12
Example 2:
javascript
// Creating buffer with size in bytevar buffer = new ArrayBuffer(20);// Creating a viewvar dataview1 = new DataView(buffer, 0, 10);// put the data 56 at slot 1dataview1.setUint32(1, 56);console.log(dataview1.getUint32(1)); |
Output:
56
Example 3: This function does not accept float value that is why it converts 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 converts this value to 3.
javascript
// Creating buffer with size in bytevar buffer = new ArrayBuffer(20);// Creating a view with slot from o to 10var dataview1 = new DataView(buffer, 0, 10);// put the value of PI at slot 1dataview1.setUint32(1, Math.PI);console.log(dataview1.getUint32(1)); |
Output:
3
Example 4: When there is no data to be stored, then it gives output as zero (0).
javascript
// Creating buffer with size in bytevar buffer = new ArrayBuffer(20);// Creating a viewvar dataview1 = new DataView(buffer, 0, 10);// putting no data at slot 1dataview1.setUint32(1);console.log(dataview1.getUint32(1)); |
Output:
0
