DataView.prototype.setUint32()

The setUint32() method of DataView instances takes a number and stores it as a 32-bit unsigned integer in the 4 bytes at the specified byte offset of this DataView.

Try it

Syntax

js

setUint32(byteOffset, value)
setUint32(byteOffset, value, littleEndian)

Parameters

byteOffset

The offset, in byte, from the start of the view where to store the data.

value

The value to set.

littleEndian Optional

Indicates whether the 32-bit int is stored in little- or big-endian format. If false or undefined, a big-endian value is written.

Return value

undefined.

Errors thrown

RangeError

Thrown if the byteOffset is set such as it would store beyond the end of the view.

Examples

Using the setUint32 method

js

const buffer = new ArrayBuffer(8);
const dataview = new DataView(buffer);
dataview.setUint32(1, 3);
dataview.getUint32(1); // 3
