setFloat64 Method (DataView)

JavaScript - Internet Explorer 10

Sets the Float64 value at the specified byte offset from the start of the view. There is no alignment constraint; multi-byte values may be set at any offset.

dataView.setFloat64 (byteOffset, value, littleEndian);

Parameters

byteOffset: The place in the buffer at which the value should be retrieved.
value: The value to set.
littleEndian: Optional. If false or undefined, a big-endian value should be written, otherwise a little-endian value should be written.

Remarks

These methods raise an exception if they would write beyond the end of the view.

Example

The following example shows how to set the first Float64 in the DataView.

JavaScript

var req = new XMLHttpRequest();
    req.open('GET', "http://www.example.com");
    req.responseType = "arraybuffer";
    req.send();

    req.onreadystatechange = function () {
        if (req.readyState === 4) {
            var buffer = req.response;
            var dataView = new DataView(buffer);
            dataView.setFloat64(0, 9.1);
        }
    }
