Buffer Module in Node.js provides access to Buffer objects that represent fixed-length sequences of bytes. readFloatLE()
is a method defined in the Buffer Class that reads a 32-bit, little-endian float from the Buffer object starting from the specified offset. The prototype of readFloatLE
is as follows:
buf.readFloatLE([offset])
offset
: Number of bytes to skip before reading. offset
must be an integer and lie in the range . The default value is .
32-bit, little-endian float from buf
starting from the specified offset.
NOTE: Buffer Class is accessible within the global scope. Therefore, you do not need to use the
require('buffer').Buffer
method to import the Buffer Module.
const buf = Buffer.from([1, 62, -83, 4, 25]);console.log(buf.readFloatLE(1));
In the first line, we create the buffer object buf
using Buffer.from()
. Then, we display the 32-bit, little-endian float value from buf
after skipping 1 byte by passing offset
1 to the buf.readFloatLE()
method.
