JavaScript dataView.getBigInt64() method
Below is the example of the dataView.setInt8() Method.
- Example:
<script>varbuffr =newArrayBuffer(12);vardataview =newDataView(buffr);document.write(dataview.getBigInt64(0));</script> - Output:
0
This getBigInt64() method is used to get a signed 64-bit integer (long long) at the particular byte offset from the start of the DataView.
Syntax:
dataview.getBigInt64(byteOffset [, littleEndian])
Parameters:
- byteOffset: This parameter specifies the offset, in bytes, from the start of the view to read the data.
- littleEndian: This is optional parameter. If it is true then indicates if the 64-bit int is stored in little- or big-endian format. If set to false or not-defined, then a big-endian value is read.
Return Value: It returns a BigInt value.
Thrown Error: If the byteOffset is passed beyond the end of the view then the RangeError is thrown.
Example 1: In this example, the offset passed is 0, so the value printed is 0 because nothing is set.
<script> // Creating buffer with size in byte var buffr = new ArrayBuffer(8); // Creating a view var dataview = new DataView(buffr); document.write(dataview.getBigInt64(0));</script> |
Output:
0
Example 2: In this example, the offset passed is 3, so the value printed is 10000 because it is set before.
<script> // create an ArrayBuffer with a size in bytes const buffr = new ArrayBuffer(16); // constant value to set const max = 10000n; const view = new DataView(buffr); view.setBigInt64(3, max); document.write(view.getBigInt64(3));</script> |
Output:
10000
