# Integer Limits

**Microsoft Specific**

The limits for integer types are listed in the following table. These limits are also defined in the standard header file \<limits.h>.

## Limits on Integer Constants

|Constant|Meaning|Value|
|--------------|-------------|-----------|
|CHAR_BIT|Number of bits in the smallest variable that is not a bit field.|8|
|SCHAR_MIN|Minimum value for a variable of type **signed char**.|-128|
|SCHAR_MAX|Maximum value for a variable of type **signed char**.|127|
|UCHAR_MAX|Maximum value for a variable of type **unsigned char**.|255 (0xff)|
|CHAR_MIN|Minimum value for a variable of type **char**.|-128; 0 if /J option used|
|CHAR_MAX|Maximum value for a variable of type **char**.|127; 255 if /J option used|
|MB_LEN_MAX|Maximum number of bytes in a multicharacter constant.|5|
|SHRT_MIN|Minimum value for a variable of type **short**.|-32768|
|SHRT_MAX|Maximum value for a variable of type **short**.|32767|
|USHRT_MAX|Maximum value for a variable of type **unsigned short**.|65535 (0xffff)|
|INT_MIN|Minimum value for a variable of type **int**.|-2147483648|
|INT_MAX|Maximum value for a variable of type **int**.|2147483647|
|UINT_MAX|Maximum value for a variable of type **unsigned int**.|4294967295 (0xffffffff)|
|LONG_MIN|Minimum value for a variable of type **long**.|-2147483648|
|LONG_MAX|Maximum value for a variable of type **long**.|2147483647|
|ULONG_MAX|Maximum value for a variable of type **unsigned long**.|4294967295 (0xffffffff)|
|LLONG_MIN|Minimum value for a variable of type **long long**|-9223372036854775808|
|LLONG_MAX|Maximum value for a variable of type **long long**|9223372036854775807|
|ULLONG_MAX|Maximum value for a variable of type **unsigned long long**|18446744073709551615 (0xffffffffffffffff)|

If a value exceeds the largest integer representation, the Microsoft compiler generates an error.
