How do you find the limit of an integer?
INT is the short form of integer.
- Formula. 2^(n-1) is the formula to find the maximum of an INT data type. In the preceding formula N (Size in bits) is the size of data type. The ^ operator calculates the power of the value.
- Output. 32 bits.
- Determine the maximum range of int. The formula is: 2^(n-1) here N=32.
