The setInt32() method stores a signed 32-bit integer (long) value at the specified byte offset from the start of the DataView.


dataview.setInt32(byteOffset, value [, littleEndian])


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


Errors thrown

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


Using the setInt32 method

var buffer = new ArrayBuffer(8);
var dataview = new DataView(buffer);
dataview.setInt32(1, 3);
dataview.getInt32(1); // 3
