Hello,

I'm designing a system and have got myself stuck.

Basically, what I'm trying to figure out is this:

If I have a 15-digit string of numbers for example:

Код:

149655893228335

How do I multiply every other number by 2? To add to this, how would I then check the result, and if the result per number is a 2-digit number, add the digits together to make it a single digit number?

I've tried using loops, and other methods but all without any luck.

My mathematics skills aren't very good.

I hope this makes sense.

Thank you,

Isolated.

What?


So you're wanting to go...

PHP код:

1*2 , 4*2 , 9*2 , 6*2 , 5*2 , 5*2 , 8*2 , e.t.c.? 


or are you meaning (by other number)

PHP код:

1*2 , 9*2 , 5*2 , 8*2 , e.t.c. 


Are you sure you need to do it this way? Seems REAL random. Like, I've never seen anyone ask this sort of thing before.

Basically, take the first four digits for example:

Код:

1 4 9 6

1*2, 9*2, etc..

So starting at 1, multiply every other number by 2, but, if like 9*2 it's a 2-digit number, like 18, you'd do 1+8 to make a single digit number(9).

The mathematics is simple enough, just converting it to pawn. A way I thought of would be to offset the array?

It's the way you mean bro?

new level = Isolated[lol][Multiplication];

((level+1)*2)

PHP код:

new string[15];
format(string, 15, "%i", strval(THE DIGIT INT));
for(new digit = 0; digit < 16; digit += 2) {
//this loops 2 4 6 8 10 12 14
new tempId = strval(string[digit+1])*2;
format(string[digit+1], 1, "%i", tempId);
}
THE DIGIT INT = strval(string); 


edit; not sure IF this works or not, Im on phone

I still don't get it, show us what will happen to your example number in details

I dont think what u want to do is possible in pawno... If it is many people wouldnt know it because thats a very weird request and i keep asking myself what u want that math for...

He wants to pick every every 2 numbers and leave 1 empty like:
149655893228335
||
\/
1*4 6*5 8*9 etc...

And then he wants to find if those numbers are superior to 10 and if they are just add them. Example:

PHP код:

new i = 6*5;
if(i > 10)
{
//the result of the multiplication is 30 so he wants to add 3+0 but idk how to separate those 2 numbers //automatically on pawno or know if it is possible.
}

Thank you everyone, I have found a solution. Let me clean it up and I'll post it.
