General Structure
The encoding assumes an octet (an eight-bit byte) where the most significant bit (MSB), also commonly known as the sign bit, is reserved to indicate whether another VLQ octet follows.
| 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
|---|---|---|---|---|---|---|---|
| 27 | 26 | 25 | 24 | 23 | 22 | 21 | 20 |
| A | Bn | ||||||
If A is 0, then this is the last VLQ octet of the integer. If A is 1, then another VLQ octet follows.
B is a 7-bit number and n is the position of the VLQ octet where B0 is the least significant. The VLQ octets are arranged most significant first in a stream.

Famous quotes containing the words general and/or structure:
“Treating ‘water’ as a name of a single scattered object is not intended to enable us to dispense with general terms and plurality of reference. Scatter is in fact an inconsequential detail.”
—Willard Van Orman Quine (b. 1908)
“With sixty staring me in the face, I have developed inflammation of the sentence structure and definite hardening of the paragraphs.”
—James Thurber (1894–1961)
