A C++ (or C) implementation can define the size of a type in bytes sizeof(type) to any value, as long as the expression sizeof(type) * CHAR_BIT evaluates to the number of bits enough to contain required ranges, and the ordering of type is still valid (e.g. sizeof(int) <= size...
When mixed with other data types in expressions, the resulting data type follows the rules shown in Numeric type promotion in expressions. An attempt to put an integer value of a larger storage size into a location of a smaller size fails if the value cannot be stored in the smaller-size...

参考stackoverflowSize of a byte in memory - Java,注意标注高亮的部分。 更多对基本类型的描述,可以查看Primitive Data Types 支持更少的 boolean 说完byte、char、short,我们再来看看对于 boolean 的描述,摘取部分信息2.3.4. The boolean Type: Although the Java Virtual Machine defines a boolean type, it on...
Variables in MATLAB®of data type (class)int8are stored as 1-byte (8-bit) signed integers. For example: y = int8(10); whosy Name Size Bytes Class Attributes y 1x1 1 int8 For more information on integer types, seeIntegers.
The size of theinttype is 4 bytes (32 bits). The minimal value is -2 147 483 648, the maximal one is 2 147 483 647. uint The unsigned integer type isuint. It takes 4 bytes of memory and allows expressing integers from 0 to 4 294 967 295. ...
It is simply an integer type that can be used as an interchange format for pointers and handles due to being the same size. Outside of specific interchange requirements, such as for passing data to a language that doesn't support pointers, a correctly typed pointer should be used to ...
Variables in MATLAB®of data type (class)int16are stored as 2-byte (16-bit) signed integers. For example: y = int16(10); whosy Name Size Bytes Class Attributes y 1x1 2 int16 For more information on integer types, seeIntegers. ...
SQL database in Microsoft Fabric Exact-number data types that use integer data. To save space in the database, use the smallest data type that can reliably contain all possible values. For example,tinyintwould be sufficient for a person's age, because no one lives to be more than 255 ye...
