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 starting at the specified byte offset of this DataView
. There is no alignment constraint; multi-byte values may be stored at any offset within bounds.
Try it
Syntax
js
setUint32(byteOffset, value)
setUint32(byteOffset, value, littleEndian)
Parameters
byteOffset
-
The offset, in bytes, from the start of the view to store the data in.
value
-
The value to set. For how the value is encoded in bytes, see Value encoding and normalization.
littleEndian
Optional-
Indicates whether the data is stored in little- or big-endian format. If
false
orundefined
, a big-endian value is written.
Return value
Exceptions
RangeError
-
Thrown if the
byteOffset
is set such that it would store beyond the end of the view.
Examples
Using setUint32()
js
const buffer = new ArrayBuffer(10);
const dataview = new DataView(buffer);
dataview.setUint32(0, 3);
dataview.getUint32(1); // 768
