## Short Abstract

In appendices to
* The Art of Computer Programming*,
Knuth lists 33
mathematical constants to 40 decimal and 44 octal places.
In this report the same constants are given to 1000 decimal and
1100 octal places. The constants were computed using the
author's MP package,
on a Univac 1108 computer.
## Comments

For a description of the constants, see the
dvi,
pdf, or
ps version of the abstract.
In early printings of * The Art of Computer Programming*,
the 44-place octal value of *pi*/180 was incorrectly rounded.
The last four octal digits were given as 1154 instead of 1155.
I won a prize of $2 by pointing out this error.

The 1000-decimal place constants are available in machine-readable form
here,
as generated by the program
test1k.f.
A small modification to the program
will give the constants to different accuracy
or in a different base.
