DataView.prototype.getInt32()

The getInt32() method of DataView instances reads 4 bytes starting at the specified byte offset of this DataView and interprets them as a 32-bit signed integer.

Try it

Syntax

js

getInt32(byteOffset)
getInt32(byteOffset, littleEndian)

Parameters

byteOffset

The offset, in bytes, 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

A signed 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 getInt32 method

js

const buffer = new ArrayBuffer(8);
const dataview = new DataView(buffer);
dataview.getInt32(1); // 0
