An unsigned integer is converted to a shorter unsigned or signed integer by truncating the high-order bits, or to a longer unsigned or signed integer by zero-extending (see the Conversions from Unsigned Integral Types table).When the value with integral type is demoted to a signed integer with...
Table of conversions from unsigned integral types See also When an unsigned integer is converted to an integer or floating-point type, if the original value is representable in the result type the value is unchanged. When the compiler converts an unsigned integer to an integer of greater size,...
The BIGINT data type takes 8 bytes of storage, and is equivalent to System.Int64 in the framework. I'm not sure where you found the information that it only stores the data in 4 bytes for smaller values, but even if so that's an implementation detail rather than a contract. So you...
Under the most common strategy for representingsignedintegral types, we can view one of the bits as a sign bit. Whenever the sign bit is 1, the value is negative; when it is 0, the value is either 0 or a positive number. An 8-bit integralsignedtype represented using a sign-bit can ...
Objects of unsigned integral types can be converted to corresponding signed types. However, such a conversion can cause misinterpretation of data if the value of the unsigned object is outside the range representable by the signed type, as demonstrated in the following example: ...
simple-type-specifier:= unsigned Theunsignedtype specifier can be used with any integral type to make the type unsigned. Unsigned integer arithmetic is always performed modulo 2n, in whichnis the number of bits in the value representation of the integer. When used alone,unsignedmeansunsignedint. ...

K&R C中关于整型提升(integral promotion)的定义为: "A character, a short integer, or an integer bit-field, all either signed or not, or an object of enumeration type, may be used in an expression wherever an integer maybe used. If an int can represent all the values of the original typ...
