DataView.prototype.getUint16()
The getUint16()
method of DataView
instances reads 2 bytes starting at the specified byte offset of this DataView
and interprets them as a 16-bit unsigned integer.
Try it
Syntax
js
getUint16(byteOffset)
getUint16(byteOffset, littleEndian)
Parameters
byteOffset
-
The offset, in byte, from the start of the view where to read the data.
littleEndian
Optional-
Indicates whether the 16-bit int is stored in little- or big-endian format. If
false
orundefined
, a big-endian value is read.
Return value
An unsigned 16-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 getUint16 method
js
const buffer = new ArrayBuffer(8);
const dataview = new DataView(buffer);
dataview.getUint16(1); // 0
