The name of the first file in this disk's directory identifies the volume,
issue number and revision of the disk. The format of this filename is:

!CDmvvii.rrr

where

! = the '!' character
m = C for C Users Journal, W for Windows/DOS Developer's Journal
vv = volume
ii = issue
rrr = revision (001 for initial release, 002 for next update, etc.)

The file UPDATE.DOC contains information about any additions or
corrections to material on the disk since the original magazine
publication.

If you have obtained this code from a floppy diskette or from CompuServe, the
headings under the column "FILENAME" represent the names of .ZIP files. All
files listed under the filename are archived in the .ZIP file.

If you have obtained this code from UUNET, the headings under the column
"FILENAME" represent the names of subdirectories. All files listed under the
"filename" are included in a subdirectory of that name.
Keywords: Jun94 C C++ Interpolation Multi-Precision Integer float streambuf

The code listings for the June 1994 issue of The C Users Journal
include source for Philip Gages's Divided-Difference Interpolation
Program, John K. Gotwals' multi-precision integer arithmetic functions,
and Tim Prince's float-precision math library, and a header for the C++
streambuf class.
