Printing hexadecimal/binary numbers

I'm trying to print the hexadecimal and binary representation of the following:
public static void main(String[] args) {
int t = 0x1;
t = t<<30;
System.out.println(0xt);
I tried to print the hexadecimal representation of t using the above, but it didn't work (I know t isn't a hex number, but I want the contents of variable t printed in hex). How can I accomplish this?
Thanks ahead.

Use the Integer class. It has methods for binary and hex:
Integer.toBinaryString(int i);
Integer.toHexString(int i);

Printing Binary Numbers in SP

I am trying to print binary numbers in my output.
Below is the expected output

You have some implicit conversion going on. Your INT column is ADDED to your VARBINARY column by
@out = @ID+''+@VolumeID
DECLARE @table TABLE (id INT, number VARBINARY(MAX))
INSERT INTO @table (id, number) VALUES
(1, 0x5F6AB40860296D4DB07C346FA12E25FD),
(2, 0x5F6AB40860296D4DB07C346FA12E25FD)
declare @vb VARBINARY(MAX), @int INT
SELECT @vb = number, @int = id
FROM @table
PRINT @vb
PRINT @int+@vb
PRINT CAST(@int AS NVARCHAR)+''+master.sys.fn_varbintohexstr(@vb)

Binary numbers to decimal numbers

Hello, Im writing a program that changes binary numbers to decimal numbers. I seem to be having a probelm calculating the last number in the binary code and adding it to the total. Also, when I use large binary numbers the output isnt anywhere near correct. help? please? thank you

public class binarynumbers
public static void main (String [] args)
int decimal=0;
Scanner scan= new Scanner(System.in);
System.out.print("enter binary number> ");
String bin=scan.next();
int zero=0;
int one=1;
int length=bin.length();
int newlen=length-1;
while (newlen>=0)
     String number = bin.substring( zero , one );
     int number1=Integer.parseInt(number);
     int squareRoot=Math.pow(2,newlen);
     decimal+=(squareRoot*number1);
     newlen--;
     zero++;
     one++;
System.out.println("The decimal number translation is " + decimal);
i did that but the math part isnt working and im getting a message like this
binarynumbers.java:26: possible loss of precision
found : double
required: int
     int squareRoot=Math.pow(2,newlen);

Recursion with binary numbers

I need to print out a list of all possiblle binary numbers with as many digits as an int k. For example, if k = 3, it would need to print out 000,001,010,011,100,101,110,111. for k = 2 it is only 00, 01, 10, 11. It is pretty clear that for any k, a recursive technique can be used to solve this problem, but I'm having trouble finding the solution. Please help. Thanks

You don't need recursion:for (int i = 0, max = 1 << (k - 1); i < max; ++i) {
print binary i to k digits
}But a recursive approach would be void increment (int[] data, int digit) {
if (digit > 0) {
--digit;
for (int i = 0; i < 2; ++i) {
data[digit] = i;
increment(data, digit);
} else {
print contents of data array
start (int k) { increment(new int[k], k); }Neither code tested.

Operations on very large binary numbers

Hi guys,
I'm trying to write a java class for manipulations of very large binary numbers.
I'm representing the BN internally as boolean[] (array of booleans false for 0 & true for 1).
I want to write an algorithm for the following operations :
shifLeft (boolean[] b,int n) : shifting binary number to left by n positions.preferably a circular shift .
and also the corresponding shiftRight() method.
can some one guide me on how to implement this ?
thanks.

Consider an array of ascii chars....
array => | |a|b|c|d|
offset = 1
len = 4In the above there are actually five spots in the
array but the offset points to the second position in
the array and the length is 4.
If I was to extract the value it would be "abcd"
because of the offset and the length.
Now a 'shift right' means that if it is "abcd" then
it should now be "abc" (because the d fell off the
end.)
I can do that like this.
array => | |a|b|c|d|
offset = 1
len = 3Notice in the above that nothing changed except the
length. But because the length changed if I
extracted the value I would get "abc" because the
offset is 1 and the length is three.
Notice also that there was no array copying.Are you sure shifting works like that ?
what I know about left shifting is that the 'd' should be moved left -toghether with a, b, c- and we append a 0 in place of 'd' .
from what you said the 'd' would be gone , or am I again wrong ?
it seems i still didn't get any satisfactory answer to this problem...

Anyone know of a way to adjust the top and side MARGINS of a document printed from iOS numbers? The default margins are too wide. Need more working space.

Open the document,
Tap the Tools icon (upper right).
Tap Document Set up.
Drag the margins to the position you wish (the actual margin width sould display as you are doing this).

Print View in Numbers 3.0

I Need to see the print view in numbers 3.0. No longer an option under "view" tab. Also the page view I'm given does not align with the preview page when actually go to print - they look different and neither has transfered my document the same from previous numbers document.

Thats it I have spent alot of time trying to re format my reports from the older version of numbers to the new, I thought for a little while I could live without the page view as i spent alot of time lining up the gold lines as page breaks but now I for some reason cant find the photos I want to use they are only listed by their date and when used in the spreadsheet, they are not where they should be when printing, Im sorry for using this forum for venting but I am absolutely P.....ed off the amount of time I have spent for nothing. I have really apple and speak very highly of them, and I just cant believe they could update a programme like this, did they even test it before they put out there. What the F is going on. sorry but Im NOT HAPPY, I think I will now go back to excell definately.

Printing: print prepared binary stream with SAPWIN

Hi .
We have a lot of different documents(MS Word, MS Excel, TIFF, PDF etc.) stored in DMS.
Now we need to print them from SAP applications using SAP printers.
For that we have an external conversion server, that could convert files to any print stream data (PCL, PLC2, PCL5, Postscript, even simple PDF).
If I use printer with simple device type (e.g. Sapscript driver is HP LaserJet PCL4/PCL5) , I just convert necessary docs into the PCL output, create programmatically a new Spool request with format G_RAW and BIN content and add PCL output to it. And this way works good. But not with SAPWIN device type.
Does anybody know, if it's possible to print prepared binary stream (PCL, Postscript or other format) using printer with SAPWIN device type? And if yes, how should I create Spool request?
Thanks in advance.

Sorry for this up.
But we still have the problem.
Any ideas?

How do i get the line/row numbers to print on my numbers document?

how do i get the row/line numbers to print on my numbers spreadsheet?

Neil,
You could make a Screen Shot with a cell selected so that the Row and Column tabs are active. That's a poor way to go about it though since the result will be a graphic with rather low resolution.
Better to make some labels yourself and add them to the Sheet before printing. You can use single row/column tables for this, or Text Boxes.

How do I set the print area in Numbers?

How do I set the print area in Numbers?

Hi Macuser4ever,
Numbers does not have the 'Set Print Area' feature. Numbers is designed around several tables, each with a purpose. For example, Input Table, Big Database, Intermediate Calculations Table (all of which you may not need to print) and a final Summary (Presentation) Table that you may wish to print. The Summary Table can be on its own Sheet. Arrange objects (Summary Table, Charts [graphs] and whatever) on one Sheet and print only that Sheet.
If you are using Numbers 3.x (Layout View and Print View missing) try this User Tip:
Print Layout Guide for Mac Numbers 3.2

Compare 2 Binary Numbers

Hi all ,
suppose I have two arbitrary lenght binary numbers (could be very large binaries).
exple : 1000111 & 11111110001
is it possible to compare them using only there 0s & 1s representations.
i.e I don't want to convert them to base 10 & compare them (probably using BigInteger).
what I'm looking for is an algorithm that compares 1000111 & 11111110001 only using there 0s & 1s sequences.
If this is possible how can I implement it ?
many thanks.

boolean equal = true;
for(inti = ar1.length, j=ar2.lenght; i >= 0 && j
=
0; i--, j--) {
if(ar1[ i ]!=ar2[j]) {
equal = false;
break;
} this code will tell you if ar1 & ar2 are equal but
won't tell you if ar1 <ar2 or ar1>ar2
how can we tell ar1 > ar2 for exple ?oh my bad.
well then indeed one would hav to start at the highest bit and embed the "shorter" value with 0's.
if the representation is in a primitive, eg. long, you cant simply write a < b since java doesnt know unsigned numbers. so either you are carefull enough and only store 31 bits in an int(like leave the highest bit alone) or you check the highest bit first, and then check the remaining.

Adding binary numbers in java please help!!

Hello all, im a total newbie to java and i need your help urgently, i have two variables
that are integers, that store binary numbers i.e.
int tmpIntOne, tmpIntTwo;
tmpIntOne = 1010;
tmpIntTwo = 1110;
i want to add these numbers together and return a binary result so far when you add them together you get:
2120
however i would like a binary result so that
result = tmpIntOne + tmpIntTwo;
= 11000
Thank you.

Hello all, im a total newbie to java and i need your
help urgently, i have two variables
that are integers, that store binary numbers i.e.
int tmpIntOne, tmpIntTwo;
tmpIntOne = 1010;
tmpIntTwo = 1110;These are not binary numbers. These are decimal numbers whose digits consist of ones and zeros. If you want to interpret the characters "010" as a binary number, then do
int tmp1 = Integer.parseInt("1010", 2);
etc.
i want to add these numbers together
int result = tmp1 + tmp;
and return a
binary result Adding two ints will give an int. Int's are always binary. If you want to display it as a binary String, as opposed to the usual decimal String, then, as suggested, use toBinaryString.

SQL Query to print 1-n numbers?

Set margins, add footer to printed pages in Numbers 3?

How do I set top, bottom & side margins & add a header and/or footer with such things as filename & date to printed pages in Numbers 3? This capability was available in previous versions, & is available with the "Setup" icon in Pages. (This icon is missing in Numbers 3)

BW,
Apple thought you might not miss Page Headers and Footers if they left it out of the new version.
You can go back to Numbers 2.3 or you can use Pages 5.0 for your publication after doing your calculations in Numbers.
