I'm not sure what you are asking for, but I know this. If you have a computer register that is used to hold integers, one bit is used for the sign. If the contents of the register are interpreted as non-negative integers, you don't need a sign bit, so you can use it for numbers that are twice as big. For example, if the register is 16 bits long, if it is used for signed integers, it can hold numbers from -215 to 215 - 1, which is to say -32,768 to 32,767. If the 16 bits are interpreted as a nun-negative integer, you get 0 to 65,535. If you mean strictly positive (excluding 0), then the register with all 16 bits 0 could be interpreted as 65,536, so the range would be 1 to 65,536. I hope that answers your question.

What is bc command in unix?

The 'bc' command is a simple binary calculator (hence the name bc). It can do simple math and uses arbitrary precision arithmetic. You can designate the scaling, precision, and other values to use in math calculations. Arbitrary precision arithmetic allows you to exceed the hardware precision of the system you are on, by scaling to any number of significant digits that you may require.


What is the purpose of the q format converter and how does it work?

The purpose of a Q format converter is to convert fixed-point binary numbers into floating-point numbers. It works by shifting the binary point to the left or right to adjust the precision of the number, allowing for more flexibility in representing values with different magnitudes.


How many symbols in an 8-bit binary number?

An 8-bit binary number consists of 8 symbols, each of which can be either a 0 or a 1. This means that there are two possible values for each bit. Therefore, an 8-bit binary number can represent a total of (2^8 = 256) different values.

What is the binary code for the number 99?

The binary code for the decimal number 99 is 1100011. In binary, each digit represents a power of 2, and when you add these values together (64 + 32 + 0 + 0 + 2 + 1), you get 99.


How many different values can be represented by 4 binary digits?

24, or 16 (0 through 15) One binary digit (bit) can have 21 values (0 or 1). Two bits can have 22 values. Three bits can have 23 values. A five-bit number can have 25 values... and so on...


What is the decimal number 23 as a binary number?

The number 23 is 10111 in binary. The digits in a binary number are exponents of 2 rather than 10, so that for a five digit number in binary, the digit places represent 16, 8, 4, 2, 1 instead of increasing values of 10. 10111 = 16+0+4+2+1 = 23
