dataview.setBigInt64(byteOffset, value [, littleEndian])
- The offset, in bytes, from the start of the view to store the data from.
- The value to set as a
BigInt. The highest possible value that fits in a signed 64-bit integer is
2n ** (64n -1n) - 1n(
9223372036854775807n). Upon overflow, it will be negative (
- Optional Indicates whether the 64-bit int is stored in little- or big-endian format. If
undefined, a big-endian value is written.
- Thrown if the
byteOffsetis set such that it would store beyond the end of the view.
var buffer = new ArrayBuffer(8); var dataview = new DataView(buffer); dataview.setBigInt64(0, 3n); dataview.getBigInt64(0); // 3n
