1. Sequence items to a single number ? How to achieve ?

Hello
Selgor here

I am working on decimal to binary conversion

I have Decimal number which is e.g. 5 and gives 101 in Binary [O.K. we all know this ]

Number 101 is stored in sequence as {1,0,1}
So seq[1]= 1 seq[2]= 0 and seq[3] = 1

how can I print each sequence item as 1 number ?

I thought that this would work :=

100x1 + 10x0 + 1x1 = 101
and it does

But can you imagine converting 13245 to binary and then writing number "my way"

There must be a simpler way

Cannot find a semblance in ref man

But as usual maybe I am not looking in the correct place
and using above

Any help appreciated

Cheers

Selgor

Hello

Selgor here

I should have given you the code

Sorry

Where would you put your code in the following
I tried but no work
It is me NOT your code

Thank you for replying
Cheers

Anticipating your reply

programme:=

include get.e 
                    sequence  seq         seq = repeat(0,30) 
    object number,n1,times,w 
                   number = 0    times = 0  n1 =0 
 
  number = prompt_number("Type a number then enter  ",{}) 
                      n1 = number 
 
      while n1 != 0 do 
         times += 1 
 
         seq[times] = remainder(n1,2) 
 
         n1 = floor(n1/2) 
 
 
       end while 
       puts(1,"\n") 
 
       for i = 1 to times do 
       puts(1,"Seq =") 
        -- puts(1,"\n") 
           	printf(1,"%4d",seq[i]) 
           	puts(1,"\n") 
	end for 
 
 
                 w= wait_key()

There's a small problem with your conversion routine (and also Selgor's). You are putting the bits into the array backwards. It doesn't show because 5 is palindromic in binary but if you try it with another number such as 13 you will see that the bits are reversed.

include std/math.e 
integer d = 5  --your decimal number 
 
sequence b = {} 
 
while 1 do 
    b = append(b,mod(d,2)) 
-- could either do  
-- b = prepend(b, mod(d,2)) -- or 
-- b = mod(d,2) & b 
    d = floor(d/2) 
    if d = 0 then 
        exit 
    end if 
end while 
 
puts(1,"{") 
for i = 1 to length(b) do 
    printf(1,"%d",b[i]) 
    if i != length(b) then 
        puts(1,",") 
    end if 
end for 
puts(1,"}")

'reverse' is not a built-in. need to have 'include std/sequence.e'

Hello Lnettnay

My apologies for the delay in answering your last post

What you have done is exactly what I wanted e.g. {1,1,0,1} as 1101

I am NOT using Eu4 but 3.1

It still works

Gives the number

But with strange characters after number on 2 new lines

I will post again

A lot quicker this time

Hope you are still with me

And while it still works O.K.

Is there a way to save the number ??

Please read next post with programme and more details

It takes me a while to organise

Cheers

Selgor

Hello all

Thank you for staying with me

The following is the programme

It works as written

I am using eu 3.1 not eu 4

I would like to place the binary number in the edit box of window

You will see all that I have tried

None works

So how does the binary number "go" into the "box"

Cheers

Selgor
