DataView.prototype.setBigInt64()
The setBigInt64() method stores a signed 64-bit integer
(long long) value at the specified byte offset from the start of the
DataView.
Try it
Syntax
setBigInt64(byteOffset, value)
setBigInt64(byteOffset, value, littleEndian)
Parameters
- byteOffset
-
The offset, in bytes, from the start of the view to store the data from.
- value
-
The value to set as a
BigInt. The highest possible value that fits in a signed 64-bit integer is2n ** (64n -1n) - 1n(9223372036854775807n). Upon overflow, it will be negative (-9223372036854775808n). - littleEndian
-
Optional Indicates whether the 64-bit int is stored in little- or big-endian format. If
falseorundefined, a big-endian value is written.
Return value
Errors thrown
RangeError-
Thrown if the
byteOffsetis set such that it would store beyond the end of the view.
Examples
Using the setBigInt64 method
const buffer = new ArrayBuffer(8);
const dataview = new DataView(buffer);
dataview.setBigInt64(0, 3n);
dataview.getBigInt64(0); // 3n
