2. What is the maximum value for an int32? - Stack Overflow

   stackoverflow.com/questions/94591

   Int32 means you have 32 bits available to store your number. The highest bit is the sign-bit, this indicates if the number is positive or negative. So you have 2^31 bits for positive and negative numbers. With zero being a positive number you get the logical range of (mentioned before) +2147483647 to -2147483648. If you think that is to small ...

3. What is the difference between int, Int16, Int32 and Int64?

   stackoverflow.com/questions/9696660

   It has minimum -32768 and maximum +32767 value. Int32. It is a FCL type. In C#, int is mapped to Int32. It is a value type and represent System.Int32 struct. It is signed and takes 32 bits. It has minimum -2147483648 and maximum +2147483647 value. Int64.

4. What range of numbers can be represented in a 16-, 32- and 64-bit...

   stackoverflow.com/questions/872544

   First off, neither IEEE-754-2008 nor -1985 have 16-bit floats; but it is a proposed addition with a 5-bit exponent and 10-bit fraction. IEE-754 uses a dedicated sign bit, so the positive and negative range is the same. Also, the fraction has an implied 1 in front, so you get an extra bit.

5. How to Declare a 32-bit Integer in C - Stack Overflow

   stackoverflow.com/questions/1229131

   If you would rather use the smallest integer type to fit a 32-bit number, then you can use preprocessor statements like the following with the macros defined in <limits.h>: #define TARGET_MAX 2147483647L. #if SCHAR_MAX >= TARGET_MAX. typedef signed char int32; #elif SHORT_MAX >= TARGET_MAX.

6. How are negative numbers represented in 32-bit signed integer?

   stackoverflow.com/questions/2931630

   to convert 5 to -5: 0000 0101 - flip -> 1111 1010 - add one -> 1111 1011. There is a trick to convert a number from positive to negative or vice verse: Adding them ignoring their signed bit (the leftmost bit) will give you 2^N (where N is the amount of the bits to represent the number). As the example above in 8-bit representation the sum of 5 ...

7. what's the largest number float type can hold? - Stack Overflow

   stackoverflow.com/questions/60224493

   The most common 32-bit floating-point format, IEEE-754 binary32, does not have eight bits for the whole number part. It has one bit for a sign, eight bits for an exponent field, and 23 bits for a significand field (a fraction part). The sign bit determines whether the number is positive (0) or negative (1). The exponent field, e, has several uses.

8. How do I declare a 32bit integer in java? - Stack Overflow

   stackoverflow.com/questions/4065776

   Integers are 32 bits wide even on 64-bit platforms. The Java language specification states quite clearly (slightly paraphrased to make more readable, in my opinion): The integral types are byte, short, int, and long, whose values are respectively 8-bit, 16-bit, 32-bit and 64-bit signed two's-complement integers, and char, whose values are 16 ...

9. What is the minimum value of a 32-bit signed integer?

   stackoverflow.com/questions/19084227

   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.

10. What is the difference between signed and unsigned int

    stackoverflow.com/questions/5739888

    95. In laymen's terms an unsigned int is an integer that can not be negative and thus has a higher range of positive values that it can assume. A signed int is an integer that can be negative but has a lower positive range in exchange for more negative values it can assume. answered Jun 29, 2015 at 4:58.

11. Count the number of set bits in a 32-bit integer - Stack Overflow
