I'm am completely stumped on a seemingly simple math formula
I need to find a way to map a set of numbers up to 4 (e.g. 1,2,3,4 or 1,2)
to any number in a range of up to 10,000 (ideally, unlimited). Such that,
(e.g. 1,2,3,4)
1 is to 1
2 is to 2
3 is to 3
4 is to 4
5 is to 1
6 is to 2
7 is to 3
8 is to 4
9 is to 1
10 is to 2
11 is to 3
12 is to 4
13 is to 1
14 is to 2
15 is to 3
16 is to 4
And so on...
Is anyone good at math, that can throw me a bone?
Thanks y'all,

Here is some simple code to solve that problem(if i have understood right):
?php
for($i = 1, $j = 1; $i = 1; $i++, $j++){
if($j == 5){
$j = 1;
print \nbr;
}
print $i is to $jbr\n;
}

I do not know if I understand well, but what about
$group=$number % 4;
if ($group==0) $group=4;

Re: [PHP] Re: PHP Math Question
I like Eric's idea of showing the values and added a form to it so you can
select the number of items to show before running the script.
?php
if(!$_POST[Submit]) {
echo form method=post action=.$_SERVER[PHP_SELF].
Maximum Number to Show: input type=text name=i size=5 value=1
input type=submit name=Submit value=Show
/form;
}
else {
for($i = 1, $j = 1; $i = $_POST[i]; $i++, $j++){
if($j == 5){
$j = 1;
print \nbr;
}
print $i. is to .$j.br\n;
} // end for

11 is to 3
12 is to 4
13 is to 1
14 is to 2
15 is to 3
16 is to 4
etc.
Here is an (untested) function that may work:
function map_four( $num )
{
$map_val = $num % 4;
if ($map_val) {
return $map_val;
} else {
return 4;
}
}
Basically, it looks like a modulus with 4, except that you want
multiples of four to return four instead of zero.
Unless, of course, I completely misunderstood the question. Which is not
uncommon as of late.

Mike sent me an email, and it seemed that he was satisfied with the script
that I made:
?php
for($i = 1, $j = 1; $i = 1; $i++, $j++){
if($j == 5){
$j = 1;
print \nbr;
}
print $i is to $jbr\n;
}
?
Good idea to rather make an interface for this, Jim!
