DataView.prototype.getFloat32()
The getFloat32() method gets a signed 32-bit float
(float) at the specified byte offset from the start of the DataView.
Syntax
getFloat32(byteOffset)
getFloat32(byteOffset, littleEndian)
Parameters
byteOffset-
The offset, in byte, from the start of the view where to read the data.
littleEndian-
Optional Indicates whether the 32-bit float is stored in little- or big-endian format. If
falseorundefined, a big-endian value is read.
Return value
A signed 32-bit float number.
Errors thrown
RangeError-
Thrown if the
byteOffsetis set such as it would read beyond the end of the view.
Description
There is no alignment constraint; multi-byte values may be fetched from any offset.
Examples
Using the getFloat32 method
var buffer = new ArrayBuffer(8);
var dataview = new DataView(buffer);
dataview.getFloat32(1); // 0
