The power used is arbitrary and can be voluntarily chosen as it happened in SI, but only for continuous values, such as physical measures. Once you leave the realm of real numbers and enter discrete mathematics (and computing), things change. Well, you can say that you do not want to write banking software (neither I), but in that case "damn much" will fit perfectly. Anyway dollar is not a SI unit. Yottadollar, attodollar sound silly. Maybe some day, after we'll stop using km/h, mph instead of m/s, Bar... - Sat, Oct 30 2004 2:46 am 3 messages, 3 authors http://groups-beta.google.com/group/comp.lang.ada/browse_thread/thread/aa463d25bcbdaa7 Question about Ada.Unchecked_Conversion - 3 new ---------------------------------- I don't have the full picture of what you're trying to do so my answer may be off the mark. When I build a custom lexor I include a (usually) 256 cell array. The cell is mapped one-to-one with (any) 256 representation of the character set in use, and 256 has the property of guaranteeing nor constraint errors. The contents of each cell is a enumeration representing the purpose of the mapped character. My lexer is built around this. For example: type enum { ign, sep, op, sym, num, hex, ... ); type enum_Map is array ( Integer range 1 ..... - Sat, Oct 30 2004 3:23 am 3 messages, 3 authors http://groups-beta.google.com/group/comp.lang.ada/browse_thread/thread/e037e74567eca23d Need statistic for Ada - all new ---------------------------------- Hi, I am planning to write a paper about how fast Ada has been adopted at work and eductaion over the last 5-10 years. Is there any statistical data about the adoption of Ada in the industries and universities? Could someone provide me some pointer? Thanks. -- Adrian Hoe http://adrianhoe.com ... - Sat, Oct 30 2004 5:04 am 1 message, 1 author http://groups-beta.google.com/group/comp.lang.ada/browse_thread/thread/61611475434bf016 generic container library - 2 new ---------------------------------- For current projects, I'm using a home-grown container library that is based on a class heierarchy. It implements the needed stream attributes and it really works rather spiffy as you build things up from the class heierarchy. If I build up all the data for a given app from the base class one single " Load" or "Store" operation and BAM! Ada takes care of it automagically. I liked the article on Charles. Its good to know that you plan on adding the necessary stream attributes since this library seems to be gaining ... - Sat, Oct 30 2004 5:36 am 2 messages, 2 authors http://groups-beta.google.com/group/comp.lang.ada/browse_thread/thread/1dd193bdbc538421 Abstract Operations On A Tagged Record - 3 new ---------------------------------- Can someone clarify my understanding (perhaps again) on abstract operations and the implications as a class heierarchy is being constructed? Specifically, what I want is something like this: A base class has an abstract operation, but I may not yet know the data types of the parameters - or possibly even the number of parameters. Let's say what I want is like this: procedure Some_ Op (<TBD Parameter List>) is abstract ; When I get to the child class, what I really need is: procedure Some_Op (Some_Param1 : in Integer;... - Sat, Oct 30 2004 6:04 am 3 messages, 3 authors http://groups-beta.google.com/group/comp.lang.ada/browse_thread/thread/6129ccd596d4814d Turning off "Unit xxx not referenced" warnings? - all new ---------------------------------- ... I thought Unreferenced (X) was newer than Warnings (Off, X)? The good thing about Unreferenced is that you get a warning if you do access the thing. The slightly confusing thing is that it sort-of means "read": eg, declaring a BC lock, which locks during elaboration, L : Lock (Some_Semaphore'Access); pragma Unreferenced (L); ... - Sat, Oct 30 2004 7:51 am 1 message, 1 author http://groups-beta.google.com/group/comp.lang.ada/browse_thread/thread/227f28d340d60167 Thank you Matthew Heaney! - 3 new ---------------------------------- ... I am able to help identify the source of Generic_Real_Arrays. (At least I know the source of *one* such library.) I have a collection that has several numeric math packages, and one from Drexel University contains Generic_Real_ Arrays.Operations. Now that I review this item, I discover that this package defines a subprogram "Singular_Value_Decomposition". By golly, that is the answer to another recent posting as well!

I guess you should be able to use distcc with later gnat or Ada-enabled gcc (although I haven't tried it specifically with Ada code, but regular compiles are distributed quite efficiantly). Here is some info on how to setup this thing: http://joetoscano.net/papers/distcc_howto.html George ... - Sat, Oct 30 2004 1:17 pm 2 messages, 1 author http://groups-beta.google.com/group/comp.lang.ada/browse_thread/thread/43d81dcde45556f0 IDE for Ada on Mac OS X? - 2 new ---------------------------------- The best IDE for Ada on Mac OS X in my opinion is XCode. I personally I use XCode, but have the source code open in an external editor, ie.
