The quote (below as taken from your link) appears in the 1968 edition. The notation [x] is often used elsewhere for one or the other of these functions, usually the former; the notation above, which are due to K.E. Iverson, are more useful, because both functions occur about equally often in practice. The function ⌊x⌋ is sometimes called the entier function, from the French word for “integer”.
There is a small difference. The 1968 edition has: "...the notations above...". (note the s).
