Infos:

• extension's page: http://smath.info/view/CurrencyUnits;
  
• requirements: SMath Studio 0.98.6047 or later (latest update);
  
• installation: SMath Studio: Tools > Plugins... > Online Gallery;
  
• sources: SVN repository;
  
• UI languages:

Functions:

• SetCurrencyUnits(1), SetCurrencyUnits(2): extends SMath Studio with currency units. When an internet connection is available, exchange rates are kept updated using the ECB reference rates (internet connection not required but useful);
  
  

  Quote

  The reference rates are usually updated by 3 p.m. C.E.T. They are based on a regular daily concertation procedure between central banks across Europe and worldwide, which normally takes place at 2.15 p.m. CET.

  
  
  
• GetYahooExchangeRate(2): get a wide set of exchange rates from Yahoo Finance (internet connection required); service discontinued by Yahoo

Thank you Martin, try with the update

Better now, but still no connectivity. I guess that is sort of firewall or proxy issue.

Unfortunately Davide, this does not work for me (Win7 x64). Plugin refuses to install properly.

very strange... try again with this update; if doens't work got to %APPDATA%\SMath\Debug\CurrencyUnits and post the log file

The results were overly wide, thus i cut them.

Failed again

Here is the log file

log.txt (1 KiB) downloaded 88 time(s).

seems a proxy/firewall authorization problem... I suppose that NetTest("http://www.google.com") and NetTest("http://www.google.de") will produce the same results

I've made another little modification, could you try again?

It seems that this plugin is not going to install into the Martins' unofficial build. I figured out by the second line of the log file.
I tried it on the official one and it seems to be Ok

thank you Radovan, now I understand
the plugin looks for the files in the %APPDATA% folder, I'll try to fix it

[EDIT] UPDATED: this version should work properly both in the official and the unofficial versions

Yes it works, thank you

In our school LAN, the connectivity is broken, at home web access works (official and unofficial version). I shall include the plugin in the next release of the inofficial distribution.

UPDATED

- error handling: LOGs will be placed in the relative "extensions\debug\CurrencyUnits" folder (so the portable version has a portable debug path)

- For developers only: added a log tool to output a Term[] tree representation (see the CurrencyUnits Implementer.cs).

---

UPDATED

- checks for network availability before each ECB update attempt;
- LOG tools updated (session start is no longer registered)
- NetTest() removed.

The yahoo download service for exchange rates has been discontinued. See their forum post.

Therefore, the function GetYahooExchangeRate() reports that the remote name could not be resolved.

I recommend to adjust the error message to "Service discontinued by Yahoo. Use function .... instead."

Perhaps some other source is available in replacement. However, I would not push this, because I rarely use it. Just cleaning up documentation.

Edit: filed as SS-3559

PLUGIN UPDATED SMath Studio 0.99.6839 and later

• [SS-3560] restored unit as input argument in SetCurrencyUnits();
  
• [SS-3559] since Yahoo service is discontinued now GetYahooExchangeRate() is hidden in the dynamic assistance and returns directly an error message if called;

PLUGIN UPDATED SMath Studio 0.99.7739 Nightly Build and later

• added Currency units (symbols) toolbox;

NOTE:

• symbols are sorted by unicode code;
  
• symbols are subject to font implementation;
  
• these are decorative symbols; you have to define yourself exchange rates on the worksheet to mix them;
