$ bc
BC> ibase=2

(standar_in) 8: syntax error
Wikipedia informs that the ops are "|, & and ^". It may be that they work only in certain BC-types or I misread something.

Redis keys are binary safe. I'd like to mess around and put binary into redis using C#. My client of choice doesn't support writing binary keys it uses keys and it make sense. However i am just fooling around so tell me how i can do this.
How do i convert a raw byte[] into a string? At first i was…

Today I had an interview where I was asked to write a program which takes a Binary Tree and returns true if it is also a Binary Search Tree otherwise false.
My Approach1: Perform an inroder traversal and store the elements in O(n) time. Now scan through the array/list of elements and check if element…

I have some C++ code from somewhere that reads and writes data in binary format. I want to see what it's reading and writing in the file, so I want to convert it's binary read and write to non-binary read and write. Also, when I convert the binary write to non-binary write, I want it to still be…

I've a few lines of code within a project, that I can't see the value of...
buffer[i] = (currentByte & 0x7F) | (currentByte & 0x80);
It reads the filebuffer from a file, stored as bytes, and then transfers then to buffer[i] as shown, but I can't understand what the overall purpose is, any…

I don't use C++ or bitwise operations at my current job but I'm thinking of applying to companies where it is a requirement to be fluent with them (on their tests anyway).
So my question is: Can anyone suggest a project which will require gaining a fluency in bitwise operations to complete?
On a…

Hi all
I am trying to do bit reversal in a byte. I use the code below
static int BitReversal(int n)
{
int u0 = 0x55555555; // 01010101010101010101010101010101
int u1 = 0x33333333; // 00110011001100110011001100110011
int u2 = 0x0F0F0F0F; // 00001111000011110000111100001111
int u3…

Hello,
I have the following problems:
First: I am trying to do a 32-spaces bitwise left shift on a large number, and for some reason the number is always returned as-is. For example:
echo(516103988<<32); // echoes 516103988
Because shifting the bits to the left one space is the equivalent…
