DataView.prototype.getUint32()

The getUint32() method of DataView instances reads 4 bytes starting at the specified byte offset of this DataView and interprets them as a 32-bit unsigned integer. There is no alignment constraint; multi-byte values may be fetched from any offset within bounds.

Try it

Syntax

js
getUint32(byteOffset)
getUint32(byteOffset, littleEndian)

Parameters

byteOffset

The offset, in bytes, from the start of the view to read the data from.

littleEndian Optional

Indicates whether the data is stored in little- or big-endian format. If false or undefined, a big-endian value is read.

Return value

An integer from 0 to 4294967295, inclusive.

Exceptions

RangeError

Thrown if the byteOffset is set such that it would read beyond the end of the view.

Examples

Using getUint32()

js
const { buffer } = new Uint8Array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9]);
const dataview = new DataView(buffer);
console.log(dataview.getUint32(1)); // 16909060
