Computers do not understand decimal notation. All information (both instructions and data) must be converted to a binary representation before the machine can understand it. We use the symbols 0 and 1 (binary notation) but the machine has a variety of physical representations it can use to encode binary data, including transistors, flux transitions, on/off switches and so on.
ticking over and getting a new no. like do the clock or some type of speedometer...
binary code(computer science) A code in which each allowable position has one of two possible states, commonly 0 and 1; the binary number system is one of many binary codes.Source: http://www.answers.com/binary+code?cat=technology
First of all we will talk about how binary number are converted back into decimal representation and later we will have program.Here is the formula of this transformation:Binary number: a3a2a1a0Decimal number a x 23 + a x 22 + a x 21 + a x 20Example:Binary: 1101Decimal: 1 x 23 + 1 x 22 + 0 x 21 + 1 x 20 = 8 + 4 + 0 + 1 = 13And here we have our program:#include #include #include int main() {char str[100];int ind;int sum = 0;printf("Please enter binary number: ");scanf("%s", str);for(ind = 0; ind < strlen(str); ind++) {sum += (str[ind] - 0x30) * pow(2, strlen(str) - ind - 1);}printf("Number in decimal would be %d\n", sum);return 0;}Testing:Please enter binary number: 1101Number in decimal would be 13Please enter binary number: 10000001Number in decimal would be 129Please enter binary number: 11111111Number in decimal would be 255Please enter binary number: 0Number in decimal would be 0
No if there was then java wouldn't have over 4 billion down loads
The Advantages are that Hovercraft can fly, or more suitably, hover over water and land, can go over rough terrain and does not pollute as much as cars.
Advantage of binary over decimal: information can be recorded and stored in any dichotomous variable: magnetised or not magnetised (most electronic media), pit or no pit (optoelectronic media CDs/DVDs). For decimal it would be necessary to store as 10 different levels of magnetisation or depths of pits. Not so easy to make such a system error-free. Advantage of decimal over binary: fewer "digits" required. Every ten binary digits (1024 values) can be replaced by just a shade more than three decimal digits (1000 values). So the number of digits to be stored is less than a third.
We have ten fingers (including thumbs) and early counting is based on one-to-one mapping onto these digits. So one reason is simple familiarity. The other advantage of counting in decimals is that fewer digits are required: 4 decimal digits takes you to over a thousand, you would need 10 binary digits to go over 1024. It gets worse with larger numbers: 7 decimal digits to go over a million but 20 binary digit. I have phones with 11 digit numbers (without the international country code). In binary, that would be a 33-digit number. No thanks!
You simply use more binary digits.
Binary is easier for the computer to understand. It is also easier to handle and is not costly.
The addition and multiplication table is much simpler. Also, on a computer it is easier to distinguish two different states than ten different states. For these reasons, modern computers do most of their calculations internally in binary.
The line over the digits that repeat in a repeating decimal.
It is relatively easy to code things in terms of on-and-off or magnetised-and-not (magnetic storage), or pit-or-no-pit (CDs). Coding in terms of 10 levels of magnetisation or ten depths of pits is much more difficiult and prone to error - both in writing and reading.
0.7525. All you have to do when turning a percent into a decimal is move over the decimal two digits to the left.
When 107 over 333 is expressed as a decimal, it becomes approximately 0.321321321..., which reveals a repeating sequence. The repeating part, "321," consists of three digits. Therefore, the smallest sequence of repeating digits has 3 digits.
It is placed over one length of repeating decimal digits.

The decimal representation of pi, as of late 2011, is over 10 trillion (1013) digits.
