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:
“Suppose we think while we talk or write—I mean, as we normally do—we shall not in general say that we think quicker than we talk, but the thought seems not to be separate from the expression.”
—Ludwig Wittgenstein (1889–1951)
“... the structure of a page of good prose is, analyzed logically, not something frozen but the vibrating of a bridge, which changes with every step one takes on it.”
—Robert Musil (1880–1942)
