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, value, littleEndian)
Parameters:
- byteOffset: This parameter specifies the offset, in bytes, from the start of the view to read the data.
- value: The value which is to be set as bigInt is given here
- 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.
Below are examples of the dataView.setInt8() Method.
Example 1:
javascript
var buffr = new ArrayBuffer(12); var dataview = new DataView(buffr); console.log(dataview.getBigInt64(0)); |
Output:
0
Example 2: In this example, the offset passed is 0, so the value printed is 0 because nothing is set.
html
// Creating buffer with size in byte var buffr = new ArrayBuffer(8); // Creating a view var dataview = new DataView(buffr); console.log(dataview.getBigInt64(0)); |
Output:
0
Example 3: In this example, the offset passed is 3, so the value printed is 10000 because it is set before.
html
// create an ArrayBuffer with a size in bytesconst buffr = new ArrayBuffer(16);// constant value to setconst max = 10000n;const view = new DataView(buffr);view.setBigInt64(3, max);console.log(view.getBigInt64(3)); |
Output:
10000
