  • What is the maximum value for an int32? - Stack Overflow
    To get max value you actually have to calculate the sum of 2^n with n from 0 to 31 or simpler 2^32 - 1 and you'll get '4294967295' as max for unsigned int, one less than anticipated
  • What is the minimum value of a 32-bit signed integer?
    The most used size of an integer is 32 bits The last bit is used to distinguish positive and negative numbers If the last bit is NOT set, then the number is positive Therefore, the maximal positive number is 0x7FFFFFFF = (1<<31)-1 = 2147483647 (the last bit is not set) For the negative numbers, two's complement notation is widely used You can identify the counterpart of the positive
  • Why has the Int32 type a maximum value of 2³¹ − 1? - Stack Overflow
    31 I know Int32 has a length of 32 bits (4 bytes) I assume it has 2³² values but as half of them must be under zero, I guess it has something to do with this I would like to know why exactly Int32 has maximum positive number 2³¹ − 1
  • java - max value of integer - Stack Overflow
    A 32 bit integer ranges from -2,147,483,648 to 2,147,483,647 However the fact that you are on a 32-bit machine does not mean your C compiler uses 32-bit integers
  • How is the max number for a $32$-bit integer calculated?
    If this 32-bit number we are talking about is unsigned, then the type in question can represent the value of 4,294,967,295, so around 4 billion, the max value an unsigned 32-bit can represent
  • What is the difference between int, Int16, Int32 and Int64?
    The only real difference here is the size All of the int types here are signed integer values which have varying sizes Int16: 2 bytes Int32 and int: 4 bytes Int64 : 8 bytes There is one small difference between Int64 and the rest On a 32 bit platform assignments to an Int64 storage location are not guaranteed to be atomic It is guaranteed for all of the other types
  • java - Why is 2,147,483,647 the max int value? - Stack Overflow
    Because the total value an int can hold in Java is 2^32 (2 to the power of 32, in other words a 32 bit number); (2^31 for negative numbers and (2^31)-1 for positive numbers and 1 for the 0)
  • What is 32-bit integer in JavaScript? - Stack Overflow
    the max 32-bit integer I believe is (2^31) which is 2,147,483,647 This is so that negative values can be stored as well (-2^31) being the 32 bit limit (this is what "signed" means)
  • Range of values in C Int and Long 32 - 64 bits - Stack Overflow
    A 32-bit unsigned int has a range from 0 to 4,294,967,295 0 to 65535 would be a 16-bit unsigned An unsigned long long (and, on a 64-bit implementation, possibly also ulong and possibly uint as well) have a range (at least) from 0 to 18,446,744,073,709,551,615 (2 64 -1)
  • Why is Int32s maximum value 0x7FFFFFFF? - Stack Overflow
    25 I saw in MSDN documents that the maximum value of Int32 is 2,147,483,647, hexadecimal 0x7FFFFFFF I think, if it's Int32 it should store 32-bit integer values that finally should be 4,294,967,295 and hexadecimal 0xFFFFFFFF My question is why Int32 stores 31-bit integer values?
