DataView.prototype.getUint32()

The getUint32() method gets an unsigned 32-bit integer (unsigned long) at the specified byte offset from the start of the DataView.

Syntax

getUint32(byteOffset)
getUint32(byteOffset, littleEndian)

Parameters

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

Return value

An unsigned 32-bit integer number.

Errors thrown

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

Description

There is no alignment constraint; multi-byte values may be fetched from any offset.

Examples

Using the getUint32 method

var buffer = new ArrayBuffer(8);
var dataview = new DataView(buffer);
dataview.getUint32(1); // 0
