[REBOL] Re: percent! - new datatype request
hi, Thanks for the stimulating thoughts... I would personally expect to see the output data type be the same as the *first* argument. I find that to be more consistent within REBOL (i.e. try appending a path to a block, now a block to a path) so if you have an integer and you subtract, add, divide it should affect the integer not the percent. and if you are dealing with a number besides 100, it should be as you said, per cent example: 200 - 50% == 100 500 + 100% == 1000 100 - 75% == 250 After all, if you don't evaluate it that way, you have lost the advantage that you get from the datatype, or at least the most obvious reason that I can see (what did you have in mind to use it for Andrew?). Give me a point of view that would logically result in a different result than I have given.

it is, just the length of the string.)

I've checked the HTML manually and the sequence of
tags is
proper set of
1. script ... /script
and then an orphan (unnoticed by browsers)
2. /script
and finally
3. script ... /script
The parsing stops just before the orphan
/script,
which I don't understand . The rule should go
beyond 2

Do this:
- Save a copy of your input.
- Cut selected pieces out of your input so that
it

breaks your rule. Save each time.
- When you can't cut any more out, look at what
you
have left, and if you can't figure it out, post

Hi Anton,

]
parse/all html rule
prin ^/
parse/all html2 rule
prin ^/

The problem is given by the interaction of remove with parse, but it is not a
bug.
At every match, parse remember the position at which the parsing process
arrived, in your example this position is exactly mark2.
When you remove at least
1 + length? mark2
chars, starting from mark1, you put mark2 (and the internal parse position
index) beyond the end of the string, like happens in this simulation:
mark1: 123
mark2: next mark1
remove/part mark1 1 + (length? mark2)
mark2
== ** Script Error: Out of range or past end
When parse restarts, it check its internal index position and sees it is
beyond the end of the string, so it stops and does not execute your :mark1
command.
You must be sure that the position of parse is not beyond the end of the
string.
You can do something like this to fix the problem:
html rule: [
any [
(print ~~~ any block ~~~)
to script mark1: (?? mark1)
thru /script mark2:
:mark1 ;go back to mark1 before removing chars
( ?? mark2
remove/part mark1 mark2
?? mark1
)
(?? mark1)
] to end
]
In our example we put the parse internal position index to the mark1 position
before removing chars and not after. So we can be sure not to invalidate the
internal position index of parse.

[REBOL] Re: percent! - new datatype request
I'm coming in to this discussion a little late, but here's the way I, personally, would see it. 100 - 50% == 50 ; as first stated This, to me, would equate to: 100 - (100 * .50) == 50 Similarly: 200 - 50% == 200 - (200 * .5) == 100 I suppose 50% - 100 == -50% ; ? or should be illegal? I don't think you could really do that, because just what is that 50% *of*? Perhaps 50% - 100% .. And 50% * 100 == 5000% 100 * 50% == 50 An interesting thought. Should 100 + 50% == 100 + (100 * .5) and 100 * 50% == 100 * .5 ? 50% * 100, though.. I can see where that would be believable. :/ Shouldn't that be 100 - 50% == 50% Not necessarily. It'd be 100 minus 50% of 100, which is 50. Otherwise, you should stick with 100% - 50% = 50%.. and thus rate: 8.25% == 8.25% price: $100.00 == $100.00 tax: price * rate == $8.25 Precisely; the datatype of the first value, the value upon which the percent is being acted, should be the returned datatype. No? taxrate: to-percent [$8.25 / $100] == 8.25% to-percent on type block! ? I don't see why. Use parens, perhaps, if you feel the need, but traxrate: to-percent $8.25 / $100 should be fine. Results in (8.25E-2 * 100), more or less. Some related, interesting behavior. You can do money! + money!, money! - money!, money! / money!, but not money! * money!. Heh. money! / money! results in number!. (I like how integer! and decimal! values all fall under the category number! .. workes nicely.) --Charles -- To unsubscribe from this list, please send an email to [EMAIL PROTECTED] with unsubscribe in the subject, without the quotes.
[REBOL] Re: Fw: percent! - new datatype request
There's always the matter that the list can take up a large part of the thought and discussion on this matter, formulate a nice proposal, submit the proposal to the list with RFC, and once people are generally satisfied, submit the final draft to RT. Save Carl some headache ;) The email I received from Carl.

I noticed that there was room in the REBOL lexicon for the N% form, and I wanted it for use in VID face specifications. What's prevented it so far has been the issue of how to deal with precision on it. I've not had the time to deal with those issues. -Carl At 6/7/02 04:18 AM +1200, you wrote: percent! - new datatype request It would be nice to see a percent datatype. It could be based on a combination of the money! and decimal! datatype. percent! datatypes would look like: 100% 1.23% 0.456% Andrew Martin ICQ: 26227169 http://valley.150m.com/ -- -- To unsubscribe from this list, please send an email to [EMAIL PROTECTED] with unsubscribe in the subject, without the quotes. -- To unsubscribe from this list, please send an email to [EMAIL PROTECTED] with unsubscribe in the subject, without the quotes.
