What is the maximum integer value 65535
65535 is the integer after 65534 and before 65536. It is the maximum value of an unsigned 16-bit integer.
What is the highest possible integer : 2,147,483,647
The number 2,147,483,647 (or hexadecimal 7FFFFFFF16) is the maximum positive value for a 32-bit signed binary integer in computing. It is therefore the maximum value for variables declared as integers (e.g., as int ) in many programming languages.
The number 2,147,483,647 remained the largest known prime until 1867. In computing, this number is the largest value that a signed 32-bit integer field can hold.
Special use in computers
1024 is the maximum number of computer memory addresses that can be referenced with ten binary switches. This is the origin of the organization of computer memory into 1024-byte chunks or kibibytes.
What is the unsigned integer 65535
65535 is the integer after 65534 and before 65536. It is the maximum value of an unsigned 16-bit integer.Strangely, the new limit, pronounced, "nine quintillion two hundred twenty-three quadrillion three hundred seventy-two trillion thirty-six billion eight hundred fifty-four million seven hundred seventy-five thousand eight hundred eight," is exactly one number off from another of the four known Mersenne primes: …In computing, 4,294,967,295 is the highest unsigned (that is, not negative) 32-bit integer, which makes it the highest possible number a 32-bit system can store in memory.
Data Types in C
| Data Type | Size (bytes) | Range |
|---|---|---|
| short int | 2 | -32,768 to 32,767 |
| unsigned short int | 2 | 0 to 65,535 |
| unsigned int | 4 | 0 to 4,294,967,295 |
| int | 4 | -2,147,483,648 to 2,147,483,647 |
Why is 16-bit 65535 : 65535 occurs frequently in the field of computing because it is 2^16-1 (one less than 2 to the 16th power), which is the highest number that can be represented by an unsigned 16-bit binary number.
What is so special about 65535 : 65535 is the product of the first four Fermat primes: 65535 = (2 + 1)(4 + 1)(16 + 1)(256 + 1). Because of this property, it is possible to construct with compass and straightedge a regular polygon with 65535 sides (see, constructible polygon).
Why is 2147483647 important
The number 2,147,483,647 remained the largest known prime until 1867. In computing, this number is the largest value that a signed 32-bit integer field can hold.
The number 2,147,483,647 (or hexadecimal 7FFFFFFF16) is the maximum positive value for a 32-bit signed binary integer in computing. It is therefore the maximum value for variables declared as integers (e.g., as int ) in many programming languages.If you are working on a system with 4-byte ints, and you set an int variable to 2,147,483,647 and then add 1, the variable will contain -2147483648.
Why is 2147483647 an important number : The number 2,147,483,647 (or hexadecimal 7FFFFFFF16) is the maximum positive value for a 32-bit signed binary integer in computing. It is therefore the maximum value for variables declared as integers (e.g., as int ) in many programming languages.
