DataView.prototype.getUint32()
The getUint32() method of DataView instances reads 4 bytes starting at the specified byte offset of this DataView and interprets them as a 32-bit unsigned integer. There is no alignment constraint; multi-byte values may be fetched from any offset within bounds.
Try it
Syntax
js
getUint32(byteOffset)
getUint32(byteOffset, littleEndian)
Parameters
byteOffset-
The offset, in bytes, from the start of the view to read the data from.
littleEndianOptional-
Indicates whether the data is stored in little- or big-endian format. If
falseorundefined, a big-endian value is read.
Return value
An integer from 0 to 4294967295, inclusive.
Exceptions
RangeError-
Thrown if the
byteOffsetis set such that it would read beyond the end of the view.
Examples
Using getUint32()
js
const { buffer } = new Uint8Array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9]);
const dataview = new DataView(buffer);
console.log(dataview.getUint32(1)); // 16909060
