Message-Id: <39c54b34.25459234@207.126.101.100>
Is there a simple way to use the range operator to check if a value
falls within?
Something like:
$num=5;
print "In range\n" if ($num == (1..20));

Why do you want to use the range operator? Why not simply:
print "In range" if $num >= 1 && $num <= 20;
??

This is a simple numerical range check with
three input arguments represented by $number,
which represents a number to compare to a range
and, $begin_range and $end_range, which sets
an inclusive numerical range. Caution should
be used regarding how large of a range is set.
Memory can be eaten up for a very large range,
if a range much like they have in Texas.
#!/usr/local/bin/perl
print "Content-type: text/plain\n\n";
$number = 5;
$begin_range = 0;
$end_range = 10;
for ($iterate = $begin_range; $iterate <= $end_range; $iterate++)
{
if ($iterate == $number)
{ print "$number is within a range of $begin_range to $end_range,
inclusive."; last; }
elsif ($iterate == $end_range)
{ print "$number is not within a range of $begin_range to $end_range,
inclusive."; }
}
exit;

ROTFLMAO!!
what texas horseshit that is!! you write a basic for loop and claim it
will use memory if it has a large number? typical moronzilla who doesn't
understand fundamental programming issues.

and why do a loop when a pair of comparisons (posted by ala) will do
fine. and your code is SLOW and will get slower as the range gets
wider.
typical crapola.
now, go away already. do your harm elsewhere.

"...for a very large range...."
Your reading comprehension skills are very typical
of a high school drop out. Your behavior is quite
stereotypical of an eight year old boy. It is
equally clear you know very little about
Perl programming.
Your illiteracy and lack of skills in Perl programming
reduces any potential dialog with you to, pointless.

Time will be used rather than memory in a loop like you coded. Typical
Texas ego! There is a single cattle station (you would call it a ranch)
here that all of Texas would fit into five times over!

heh heh heh!
a simple for loop is not affected by the RANGE of its values in any way
shape of form. it is a simple increment and that does not affect
memory. the .. range operator can be a memory hog if used with a large
range, but you talked about your code here:
G> This is a simple numerical range check with three input arguments
G> represented by $number, which represents a number to compare to a

is that not talking about your for loop code? can you answer with a
simple yes or no?
tell me which uses more memory:
for( $i = 0 ; $i < 100 ; $i++ ) {
or
for( $i = 0 ; $i < 1_000_000_000 ; $i++ ) {
answer that as well. just pick the one which uses more memory

No, Kira, I'm afraid he's right. These two loops consume the
same amount of memory:
for ($i = 1; $i <= 100; $i++) {
$sum = $sum + $i;
}
and
for ($i = 1; $i <= 10000000; $i++) {
$sum = $sum + $i;
}
The size of the range isn't what matters. It's what you do with it.
Sure, if you built an array with a huge range, the array would get
proportionately bigger, but your "testing" code merely gets slower as
the range gets bigger.
And the simple comparison posed by others beats your "for" loop by
far, except for the extreme case of the range being only one or two
elements long. {grin}

Time ~ Memory, perhaps splitting hairs. Time would be
a closer technological term, however memory is used
for a long time, much like your being nowhere for
a long time. I will concede, if you choose to speak
Techno-Geekster Gibberish, which I do not, a lot
of processing time will be consumed for a large range
and, a block of memory will be unavailable, for an
equally long time. Memory is gobbled up. Slippery
Semantics for an English teacher; reading comprehension
challenges for a Techno-Geekster.
Fine hairs, I have, as any of my telescope neighbors
will comment, least during cool Fall, Winter and Spring.
In Oklahoma, our mosquitoes are so large, we use their
wings to roof our farm houses, barns and chicken coops,
one wing being enough to do a large farmstead.

No, Randal, Mr. Buttman is dead wrong as usual due to
his exceptionally high rate of illiteracy. Read his
comments again, for comprehension. As usual, he shot
his mouth off before loading his brain.

Yes. See my other article for comments on Techno-Geekster
comprehension and plain English comprehension. Should a
range be built with an array, of course, you are right,
memory would be eaten up like crazy by a large range array.
> And the simple comparison posed by others beats your "for" loop by

Nope. Other codes pale compared to what my code does and has
potential to do. Consider an associative array of data, for
example, lab results containing a test number, control quality,
test results and other data such as comments. Easy enough to
enclose my code within a foreach array construct to look for
certain criteria, numerically. If 'control quality' is rated
0 to 10, 0 being no controls, 5 being average, 10 being excellent..
very easy to use this construct to parse out control quality
by a numerical rating from an associative array of data.
Other codes posted, yes, they work but don't do anything
close to what my code does, nor do they have the potential my
code has. This is clear as other codes do not allow for input
arguments nor print a user readable statement as to results.
My long experience as a woman has taught me shorter is often not better.
