A UINT8 is an 8-bit unsigned integer (range: 0 through 255 decimal). Because a UINT8 is unsigned, its first bit (Most Significant Bit (MSB)) is not reserved for signing. This type is declared as follows:
Learn how to create, convert, and use variables of type uint8 in MATLAB. See examples, syntax, and extended capabilities for tall arrays, C/C++ code generation, GPU arrays, and distributed arrays.
Learn what uint8_t is, why use it, and how it works in C and C++ programming languages. Find tips and examples for working with binary data, avoiding overflow errors, and using bitwise operators with uint8_t.
Learn what uint8_t and other integer types mean in C programming, and how they store values in bytes and bits. See examples of how to use them and their ranges with a huge value.
A discussion on the advantages and disadvantages of using uint8_t over unsigned char in C programming. Learn about the differences, the standards, the platforms, and the opinions of various C programmers.
Learn how to use uint8, an unsigned 8-bit integer type in C++, for memory efficiency and binary data. See syntax, operations, examples, and common pitfalls of uint8.
The implementation may define typedef names intN_t, int_fastN_t, int_leastN_t, uintN_t, uint_fastN_t, and uint_leastN_t when N is not 8, 16, 32 or 64. Typedef names of the form intN_t may only be defined if the implementation supports an integer type of that width with no padding. Thus, std::uint24_t denotes an unsigned integer type with a width of exactly 24 bits.
Uint8Array represents an array of 8-bit unsigned integers, initialized to 0 unless otherwise specified. It has methods to create, serialize, and modify Uint8Array data from hex and base64 strings.
Optimized for speed. Thus a uint8_t is guaranteed to be exactly 8 bits wide. A uint_least8_t is the smallest integer guaranteed to be at least 8 bits wide. An uint_fast8_t is the fastest integer guaranteed to be at least 8 bits wide. So the extended integral types help us in writing portable and efficient code.
The C language defines several integer data types: integer, short integer, long integer, and character, all in both signed and unsigned varieties. The GNU C compiler extends the language to contain long long integers as well.
