This is a feature of C# 9.0. ... but it is possible to define conversion operators. Array indexing ([ ]) ... 16-bit (2-byte) 0: int: System.
Blittable types are data types in the Microsoft .NET Framework that have an identical presentation in memory for both managed and unmanaged code. Understanding the difference between blittable and non-blittable types can aid in using COM Interop or P/Invoke, two techniques for interoperability in .NET applications.
For example, 32 contiguous bits may be treated as an array of 32 Booleans, a 4-byte string, an unsigned 32-bit integer or an IEEE single precision floating point value. Because the stored bits are never changed, the programmer must know low level details such as representation format, byte order, and alignment needs, to meaningfully cast.

Convert to an int64 (on the stack as int64) and throw an exception on overflow. Base instruction 0x85 conv.ovf.i8.un: Convert unsigned to an int64 (on the stack as int64) and throw an exception on overflow. Base instruction 0xD5 conv.ovf.u: Convert to a native unsigned int (on the stack as native int) and throw an exception on overflow. Base ...
For unsigned integers, the bitwise complement of a number is the "mirror reflection" of the number across the half-way point of the unsigned integer's range. For example, for 8-bit unsigned integers, NOT x = 255 - x , which can be visualized on a graph as a downward line that effectively "flips" an increasing range from 0 to 255, to a ...
Integer addition, for example, can be performed as a single machine instruction, and some offer specific instructions to process sequences of characters with a single instruction. [7] But the choice of primitive data type may affect performance, for example it is faster using SIMD operations and data types to operate on an array of floats.
A variable-length quantity (VLQ) is a universal code that uses an arbitrary number of binary octets (eight-bit bytes) to represent an arbitrarily large integer. A VLQ is essentially a base-128 representation of an unsigned integer with the addition of the eighth bit to mark continuation of bytes. VLQ is identical to LEB128 except in endianness ...
