- Measurements - - http://mattmccutchen.net/measurements/ - - Written and maintained by Matt McCutchen - -This OpenOffice.org Calc add-in provides a basic set of spreadsheet functions -for manipulating scientific measurements, tracking units of measure and -significant figures. - -This is version 1.2. - -To use ------- -- You might like to look at the included demo spreadsheet, - measurements-demo.ods . - -- Input a measurement as a string consisting of a floating-point numerical - value (scientific notation preferred), a space, and a unit expression. The - unit expression consists of one or more unit symbols, each optionally raised - to an integer power with ^, and separated by *, space (implied multiply), or - / (inverts the rest of the expression). Example: 1.20E3 kg*m^2/s^2 . - Only a few units are supported so far; see the list in - src/net/mattmccutchen/measurements/Unit.java . - -- The number of significant figures is inferred from your entry. You can - indicate that a number is exact by following it with a lowercase x. - -- A measurement that does not contain a space is interpreted as an exact pure - number (because the spreadsheet forgets the number of sig figs entered by the - user anyway). To enter an inexact pure number, enter a formula containing a - literal string with a trailing space: ="1.497 " . - -- Use the M* functions (MADD, MSUB, MMUL, MDIV, MNEG, MPOWINT, MROOTINT, MPOW, - MEXP, MLN) to do arithmetic on measurements. A computed result shows up as a - scientific-notation value to the correct number of significant figures and - units (for your benefit) followed by a code containing the add-in's - representation of the result (including precision beyond the significant - figures). Example: If mass is in A1 and volume is in A2, put this in A3 to - compute the density: =MDIV(A1;A2) . - -- The difference between MPOWINT and MPOW is that MPOW lets you use a - pure-number measurement for the exponent but requires the base to be a pure - number, while MPOWINT lets you use a base with units but requires the exponent - to be an integer. - -- To have a computed result shown in units other than the default, pass it and - the desired unit expression to MSTRAS. Example: =MSTRAS("1 m^3";"L") . This - affects only the user-friendly form, not the code. - -- If you're picky and want to show the user-friendly form of a result without - the code, use MCLEANSTR. There is also MCLEANSTRAS. - -- If you see ERROR, something went wrong, but you have to guess what. :) A - future version might have better diagnostics. - -If you find bugs (which are almost certain to exist), please report them to me! - -To build --------- -I build the add-in against the OpenOffice.org 3 SDK included with Fedora using -the Eclipse Java builder for the Java code and a makefile for the other steps. -This sequence builds the installable add-in (measurements.oxt): - -$ . ./shell-setup -$ make bin-types -Refresh and build the project in Eclipse -$ make - -I'm not really confident in what I'm doing here, so your mileage may vary, -especially with other packagings of the SDK. - -Legal ------ -Measurements consists of: - -- Robert Harder's Base 64 encoder/decoder ( http://iharder.net/base64 ), which - he has placed in the public domain - -- Code by me, Matt McCutchen, which I hereby place in the public domain - -Measurements comes with absolutely no warranty. - -~~~~ +The "ooo-api" project exports all the OOo jars so that the Measurements Java +code can compile against them. You may need to adjust the build path to match +your version of the OOo SDK. \ No newline at end of file diff --git a/measurements-demo.ods b/measurements-demo.ods deleted file mode 100644 index

Encodes and decodes to and from Base64 notation.

- *

Homepage: http://iharder.net/base64.

- * - *

- * Change Log: - *

- *
    - *
  • v2.2.1 - Fixed bug using URL_SAFE and ORDERED encodings. Fixed bug - * when using very small files (~< 40 bytes).
    • - *
  • v2.2 - Added some helper methods for encoding/decoding directly from - * one file to the next. Also added a main() method to support command line - * encoding/decoding from one file to the next. Also added these Base64 dialects: - *
      - *
    1. The default is RFC3548 format.
      2. - *
    2. Calling Base64.setFormat(Base64.BASE64_FORMAT.URLSAFE_FORMAT) generates - * URL and file name friendly format as described in Section 4 of RFC3548. - * http://www.faqs.org/rfcs/rfc3548.html
      3. - *
    3. Calling Base64.setFormat(Base64.BASE64_FORMAT.ORDERED_FORMAT) generates - * URL and file name friendly format that preserves lexical ordering as described - * in http://www.faqs.org/qa/rfcc-1940.html
      4. - *
    - * Special thanks to Jim Kellerman at http://www.powerset.com/ - * for contributing the new Base64 dialects. - *
    • - * - *
  • v2.1 - Cleaned up javadoc comments and unused variables and methods. Added - * some convenience methods for reading and writing to and from files.
    • - *
  • v2.0.2 - Now specifies UTF-8 encoding in places where the code fails on systems - * with other encodings (like EBCDIC).
    • - *
  • v2.0.1 - Fixed an error when decoding a single byte, that is, when the - * encoded data was a single byte.
    • - *
  • v2.0 - I got rid of methods that used booleans to set options. - * Now everything is more consolidated and cleaner. The code now detects - * when data that's being decoded is gzip-compressed and will decompress it - * automatically. Generally things are cleaner. You'll probably have to - * change some method calls that you were making to support the new - * options format (ints that you "OR" together).
    • - *
  • v1.5.1 - Fixed bug when decompressing and decoding to a - * byte[] using decode( String s, boolean gzipCompressed ). - * Added the ability to "suspend" encoding in the Output Stream so - * you can turn on and off the encoding if you need to embed base64 - * data in an otherwise "normal" stream (like an XML file).
    • - *
  • v1.5 - Output stream pases on flush() command but doesn't do anything itself. - * This helps when using GZIP streams. - * Added the ability to GZip-compress objects before encoding them.
    • - *
  • v1.4 - Added helper methods to read/write files.
    • - *
  • v1.3.6 - Fixed OutputStream.flush() so that 'position' is reset.
    • - *
  • v1.3.5 - Added flag to turn on and off line breaks. Fixed bug in input stream - * where last buffer being read, if not completely full, was not returned.
    • - *
  • v1.3.4 - Fixed when "improperly padded stream" error was thrown at the wrong time.
    • - *
  • v1.3.3 - Fixed I/O streams which were totally messed up.
    • - *
- * - *

- * I am placing this code in the Public Domain. Do with it as you will. - * This software comes with no guarantees or warranties but with - * plenty of well-wishing instead! - * Please visit http://iharder.net/base64 - * periodically to check for updates or to contribute improvements. - *
