Subject: v34i023: fformat - C++ class for formatting floating point numbers, Part01/01
Message-ID: <1992Dec13.013912.26325@sparky.imd.sterling.com>
X-Md4-Signature: 203cfd1b465072f658aab68596cdf158
Date: Sun, 13 Dec 1992 01:39:12 GMT
Approved: kent@sparky.imd.sterling.com

Posting-number: Volume 34, Issue 23
Archive-name: fformat/part01
Environment: C++
WHAT IS FFormat?
================
FFormat is a C++ class that is designed to output formatted
floating point numbers (float, double, etc.). By formatted I mean:
1,234,567.8901 2345
FFormat can format to a specified total character width, if the
number doesn't fit it will be divided down until it does and then
the appropriate SI notation will be affixed. For instance, if
you gave IFormat the number 1234567 and set the width to 6 you would
get:
1,235K
Note that this is just a class to be plugged into your programs. It
is not a standalone program.
WHAT IS TFormat?
================
TFormat is a template version of FFormat (actually a subclass of
FFormat) that is designed to be flexible enough to plug in your own
extended numeric classes. For instance, I have successfully used
g++'s Integer class with TFormat. I have also given an example
class (Money) that does the minimum necessary to work with
TFormat (ex. output $1,234,567.89).
OTHER FEATURES
==============
You can change the comma or the space to different characters and the
width of each grouping as well. For instance you could have
1234'5678.901,123
(here, SetSepWidth(4); SetSep('\''); SetDeciWidth(3); SetDeciSep(',');)
You can change the SI postfixes to be different. For instance, you
might like K=1,024 instead of 1,000.
You can toggle whether to use SI postfixes, right adjusting, and
whether separators are used. You can allow scientific notation (ex.
1.23e+999).
Can be used with non-floating point values like int, long.
EXAMPLE
=======
FFormat FForm;
cout << FForm.Str(1234567.890123) << endl;
outputs -> 1,234,567.8901 23

X
XWHAT IS TFormat?
X================
X
XTFormat is a template version of FFormat (actually a subclass of
XFFormat) that is designed to be flexible enough to plug in your own
Xextended numeric classes. For instance, I have successfully used
Xg++'s Integer class with TFormat. I have also given an example
Xclass (Money) that does the minimum necessary to work with
XTFormat (ex. output $1,234,567.89).

Xwidth of each grouping as well. For instance you could have
X 1234'5678.901,123

X
XSee fformat.h for more information.
X
XTESTING
X=======
X
XUNIX
X====
X
X Edit the Makefile for either CC or g++ (g++ by default).
X Run the Borne shell "test.sh" which will compile and run the
X demo program. The shell also runs "diff" to see if your output
X is identical with my output.
X
XDOS
X===
X
XRename all the .c files to .cc (or .cpp or whatever your standard is).
X
X Borland
X -------
X Either edit the file "make.bor" or open a new project and add the
X two (renamed) files to the project list. Press F9 to make (as usual).
X -or-
X If you edited the file "make.bor" then run "make -f make.bor".
X
X GCC
X ---
X Edit the file "makefile". Uncomment "CC=gcc" change the extension
X to "C=.cc" and run "make test".
X Edit the file "test.bat" so that it will run go32.
X
X Both
X ----
X Run "test.bat"
X
XEXAMPLE
X=======
X
X FFormat FForm;
X cout << FForm.Str(1234567.890123) << endl;
X
Xoutputs -> 1,234,567.8901 23

X// Description
X// ===========
X//
X// FFormat is a C++ class that is designed to output formatted
X// floating point numbers (float, double, etc.). By formatted I mean:
X// 1,234,567.8901 2345
X//
X// TFormat is a template version of FFormat (actually a subclass of
X// FFormat) that is designed to be flexible enough to plug in your own
X// extended numeric classes. For instance, I have successfully used
X// g++'s Integer class and Fix class. I have also given a minimal
X// example of a Money class where "Money" uses a long to store its
X// value and divides the value by a 100 to get dollars and cents. It
X// also show's that FFormat can handle funny leading characters like
X// the dollar sign with no probs.
X//
X// OTHER FEATURES
X// ==============
X//
X// FFormat can format to a specified total character width, if the
X// number doesn't fit it will be divided down until it does and then
X// the appropriate SI notation will be affixed. For instance, if
X// you gave IFormat the number 1234567 and set the width to 6 you would
X// get:
X// 1,235K
X//
X// You can change these values if you prefer the computer science
X// K = 1,024, for instance.
X//
X// IFormat will, by default, right adjust number if the ouput is smaller
X// than the width passed. Where a width of 0 signifies variable width.
X// For instance, here's 123 with a width of 5 (vertical bars for clarity)
X// | 123|
X//
X// You can toggle whether to use SI postfixes, right adjusting, and
X// whether separators are used.
X//
X// DEFAULTS
X// ========
X// putseps = true (use the separator characters)
X// width = 0 (unlimited length of output)
X// use_si = true (that is, if width set to something)
X// right_adjust = true (numbers are right adjusted)
X// sep = ',' (comma is integer separator)
X// sep_width = 3 (123,456 etc. in groups of 3)
X// deci_sep = ' ' (space is the fractional part separator)
X// deci_width = 4 (.1234 5678 etc. in groups of 4)
X// precision = 0 (unlimited)
X// allowexp = 0 (do not use exponent notation)
X//
X// By default the postfixes are:
X// Kilo 'K' 1E3 Milli 'm' 1E-3
X// Mega 'M' 1E6 Micro 'u' 1E-6 (or the mu character)
X// Giga 'G' 1E9 Nano 'n' 1E-9
X// Tera 'T' 1E12 Pico 'p' 1E-12
X// Penta 'P' 1E15 Femto 'f' 1E-15
X// Exa 'E' 1E18 Atto 'a' 1E-18
X//
X// WIDTH
X// =====
X// When specifying a width to shoot for, FFormat goes into a different
X// mode. In fact most of the code deals with the problems we get when
X// a width is specified. Here's a synopsis of what happens.
X// - If the string fits, great. Right adjust if necessary.
X// else if it doesn't fit then
X// - If the number is not tiny then
X// - chop off as many decimal places as needed to make it fit.
X// - If that doesn't work,
X// - Divide the number by the minimum SI value to make it fit.
X// else if the number is tiny (like 1E-10) then
X// - chop off as many decimal places as needed to fit (but leave 1)
X// - if that doesn't work,
X// - Divide the number by the largest SI value (ex. micro) to make
X// it fit.
X//
X// DYNAMIC ALLOCATION
X// ==================
X// The string pointer "work" is dynamically allocated (with new and
X// delete). You can safely delete work if you need the space, just
X// make sure that work points to NULL before you call Str() again.
X// If you haven't deleted "work" then the space will be either a)
X// re-used if the new number will fit, or b) deleted and a new (larger)
X// block of memory allocated. It is better, therefore, to print your
X// large numbers first and work down to your smaller numbers later to
X// prevent heap fragmentation. Alternatively, use Str(1E100), for instace,
X// to get FFormat to make a lot of space available.
X//
X// TO DO
X// =====
X// I guess some people would like even more formatting features. Like:
X// - Aligning numbers at the decimal point.
X// - Allowing a space between the SI postfix and the numbers.
X// - Allowing limits with the postfix notation. i.e. allow the use of
X// K for 1,000 but not the use of M or higher.
X// - It could be smarter about using exponents.
X// - Could eliminate one or both separators in order to squeeze the
X// number in the width asked for.
X// - Make it faster.
X// - I wanted to use "locale.h" to figure out the standards for the
X// system, but I found the functions didn't work very well. I think
X// that someone with more experience with these problems should make
X// a "locale" aware subclass of FFormat. (and send it to me!)
