Binary Definition and 569 Threads

i'm doing a project on electronics while knowing nothing at all about it. after reading up i do have some basic info, but i think i also have quite a bit of misconception. based on internet research ,i know that RAM is created by semiconductors ( please correct me if I'm wrong) and binary...

I’m hoping that someone will be able to clarify these questions that I have been given as I’m very confused. 1. Convert 56 832 into a 32-bit floating binary representation. 2. Convert the 32-bit floating point binary representation B28C0F34 into decimal. I have watched a couple of...

binary long division - updated with actual example Basically what I'm asking is when is a digit in the quotient 0? This is from an exercise where I'm supposed to fill in the boxes. I don't understand how they completed the parts that are given to me. Why is the first number 1 when 1111>1010

The title speaks for itself. I'm just curious and I couldn't find anything on it. Particularly, what if they are a close binary (period less than 50 days)?

Homework Statement I don't know how to convert the number 148.3 to binary form. Homework Equations Just having a decimal point really throws in a monkey wrench in the "keep dividing by and if a number halfed has a decimal point ignore the after decimal point stuff two" procedure...

Hi :-) I have questions regarding the binary properties of numbers. I would like to discuss some very specific attributes of "scalar" values. IF the goal is to compile a pattern recognition algorithm instead of training it with test sets, Then I am investigating a method for the compilation of...

Homework Statement Design a digital system that multiplies two binary numbers by the repeated addition method Homework Equations The Attempt at a Solution

Hello, I'm wondering if there are any tricks to quickly determine the parity of the weight of a binary number, i.e., whether it's even or odd. I'm not interested at all in the actual weight of the number, but in the parity of it. I know that if say x = a XOR b, then x has odd weight iff...

Use a loop to read (charAt()) each digit (0/1 char) in the input string, scanning from right to left; Use the loop to build the required powers of 2; Use a conditional statement to deal with 0 and 1 separately; Debug using simple input, e.g. 1, 10, 101, and print intermediate values in...

Hi, For example, say we have the binary integer 101010 and I split it into blocks, say (1)(01)(01)(0). The size of the blocks is determined by some function. We want to count the number of '1' bits inside each of these blocks. I'm interested in a fast C++ code to do this. There are fast...

I have been with this to some forums but it didn't help and I was advised to come to this one, so here is the question. My task is to compute given N - length binary series and P = p(0) and 1-P = p(1) expected number of consecutive occurence of 0 or 1 of k - length. For example 10011100 has...

Hi, All: Just curious as to whether there is some sort of canonical extension of the standard binary connectives: and, or, if, iff, etc. , to n-valued logic. I imagine this may have to see with Lattices, maybe Heyting Algebras, and Order theory in general. Just wondering if someone...

Dear all I am trying to fit a simple ARCH(1)/GARCH(1,1) model to a set of binary data, i.e. I assume a latent GARCH process that is only observed at the values a and b, say (whenever it crosses or hits those thresholds). I found some ideas on fitting a censored GARCH (by SX Wei, for example...

How do you open a binary file in command in Pelles C so that it is readable?

In a white dwarf acreting binary we would make distinction between thsoe with weak magnetic field that make an acretion disc and those with strong magentic fields where the material from the larger star gets funneled along the field lines. But in a black hole binary all of the energy is...

The acretion process between a white dwar binary and blakc hole binary is significantly different as the black hole has no solid surface. So am I right to presume that a neutron star binary should be the same process but with higher energies than than white dwarf case?

I'm trying to divide 1011001 / 10 using the non-restoring division method. This is what i get: http://prntscr.com/8aecs . The remainder is not correct(it should be 0001 and I'm getting a 0111) and I'm wondering where is the mistake.. I've checked about 10 times and i don't see the problem. Can...

how can you tell if a binary number is negative or positive? 1111 <--- how do you know if this is 15 or -1? and for my project i have to make a 4 bit subtracter using LED lights to show 1's or 0's. Do I just leave it in 2's complement form?

Why is it that when using 2's complement, the result of arithmetic operations differ by two? 11011001 (-39) + 11100111 (-25) = 11000000 (which is -62 in 2's complement, even though it's supposed to be -64) 00110011 (51) + 11101110 (-16) = 00100001 (33, but it's supposed to be 35)
