Syntax
dataview.setFloat64(byteOffset, value [, littleEndian])
Parameters
- byteOffset
- The offset, in byte, from the start of the view where to store the data.
- value
- The value to set.
- littleEndian
- Optional Indicates whether the 64-bit float is stored in little- or big-endian format. If false or undefined, a big-endian value is written.
Return value
Errors thrown
RangeError
- Thrown if the
byteOffset
is set such as it would store beyond the end of the view.
Examples
Using the setFloat64
method
var buffer = new ArrayBuffer(8); var dataview = new DataView(buffer); dataview.setFloat64(0, 3); dataview.getFloat64(0); // 3
