Re: standalone has plainly readable transcript
As a documentation professional, Hmmm Amateur with delusions of grandeur? (Actually, on my private web page you find my main claim to fame.) surely you recognize the dynamic that occurs once the meme of the docs are inadequate grows legs: Yeah. Point taken, and apologies for the overly broad generalisation. Given your experience, what specific remedies would you recommend? I haven't started working with version 2 yet, so with the proviso that I haven't seen the updated docs: I think a lot of complicated systems are complicated partly because of the interactions between the parts, not the number of parts or any intrinsic property of them as such. Thus I favour a style of explanation where the explanation by command/keyword or even by category is secondary to one by topic. As an alternative to topic, think environment, taking that word fairly in the abstract. An environment is only partly a distinct part of the system, it is also a mode of working, or a set of common idioms to work with. Identifying these topics/environments is a good way to bring together conceptually related commands and keywords. Remember the I should have made the connection comment that triggered my initial post? I think the big advantage to this approach is that you make a number of these connections for the reader. Instead of emphasis on desrcribing commands and keywords you get an emphasis on describing common idioms, ready-made connections between the commands and keywords. Of course you can't give all possible connections in a manual, but giving a number of them gives the reader a more operative definition, rather than a dictionary definition.

For anyone who does numerical work I highly recommend the Numerical Recipes books.

However, coding systems solution (the standard answer to how do I invert a matrix is you don't; you probably only need to solve a system) in an interpreted language wil be very slow compared to even a straight Fortran or C code, let alone an optimised code.

Re: Rev math
Yes. Use 14. (49 bits floating point) Use less if you need exact equality. Thanks, Dar. So, does that mean we can take numbers of any length, go ahead and perform the operation, and then trust the result to 14 digits, Well, the usual roundoff error analysis of floating point arithmetic still applies. You can always come up with computations that completely lose your accuracy. For instance, suppose that a=0.12345678901234 is the result of a computation and is accurate to these 14 digits, and b=0.12345678901233 is likewise accurate to 14 digits, then a-b is 0.10 times 10-to-the-minus-fourteen, but it's only accurate to one digit. or do we first have to first preprocess the operands to a certain number of digits according to the type of operation? No, you must avoid operations that are inherently inaccurate. For instance, in the formula for the solutions of a quadratic equation only one of the plus/minus possibilities is guaranteed to be accurate. For a stable computation of the second you need to use a different formula completely. Numerical accuracy is not trivial. Most people don't see it until they take a (graduate?) course in numerical mathematics or computational computer science. -- Victor Eijkhout [EMAIL PROTECTED] tel: 865 974 9308 (W), 865 673 6998 (H), 865 974 8296 (F) http://www.cs.utk.edu/~eijkhout/ ___ use-revolution mailing list [EMAIL PROTECTED] http://lists.runrev.com/mailman/listinfo/use-revolution

RE: If this is a feature, it's a nasty one.
It seems more logical to always assume variables will be evaluated prior to script execution. Yes, but the man page doesn't say that it's a variable: it says that the iproperty/i thing in the set statement is the name of a property. The name. Not a variable evaluating to a name. And I think that needs to be pointed out explicitly, because the obvious possibilities are 1/ only the actual name is allowed 2/ any expression giving a name. I don't understand at all why here only a name or a variable is allowed. -- Victor Eijkhout [EMAIL PROTECTED] tel: 865 974 9308 (W), 865 673 6998 (H), 865 974 8296 (F) http://www.cs.utk.edu/~eijkhout/ ___ use-revolution mailing list [EMAIL PROTECTED] http://lists.runrev.com/mailman/listinfo/use-revolution

That is clearly not true in the above case. It also says Any parameters are evaluted, giving send mouseup 1+1 as example. That is less than the whole truth: based on this I would write send tt the aaa of me which of course is completely incorrect. Anyway, solution: send tt quote the aaa of me quote I guess the correct statement would be send expr to whatever : the expr is an expression that yields a string of the form command arg1,arg2, The argn expressions are evaluated in the corrent context, and the resulting command is sent to the whatever handler. Ok, quiz time: what is the output of on t arg1,arg2 put arg1 end t on tt set the aa of me to 3,4 send t the aa of me to me end tt (I guess, for clarity, another clause is could be added in the above definition.) -- Victor Eijkhout [EMAIL PROTECTED] tel: 865 974 9308 (W), 865 673 6998 (H), 865 974 8296 (F) http://www.cs.utk.edu/~eijkhout/ ___ use-revolution mailing list [EMAIL PROTECTED] http://lists.runrev.com/mailman/listinfo/use-revolution
