System.IntPtr; System.UIntPtr; System.Single; System.Double; Additionally, one-dimensional arrays of these types (including unsafe fixed buffers) as well as complex types containing only instance fields (which includes readonly fields) of these types are blittable. The presence of static or const fields that are non-blittable does not cause the ...
Also, the first implementation will return false for any NaN value, but the latter might return true for NaN values with the sign bit set. Lastly we have the problem wherein the storage of the floating point data may be in big endian or little endian memory order and thus the sign bit could be in the least significant byte or the most ...
Array, a sequence of elements of the same type stored contiguously in memory; Record (also called a structure or struct), a collection of fields . Product type (also called a tuple), a record in which the fields are not named
intptr is a new alias with the pointer type int *. The definition, intptr ptr;, defines a variable ptr with the type int *. So, ptr is a pointer which can point to a variable of type int. Using typedef to define a new pointer type may sometimes lead to confusion. For example:
A singly-linked list structure, implementing a list with three integer elements. The term list is also used for several concrete data structures that can be used to implement abstract lists, especially linked lists and arrays. In some contexts, such as in Lisp programming, the term list may refer specifically to a linked list rather than an array.
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.
In other array types, a slice can be replaced by an array of different size, with subsequent elements being renumbered accordingly – as in Python's list assignment A[5:5] = [10,20,30], that inserts three new elements (10, 20, and 30) before element "A[5]". Resizable arrays are conceptually similar to lists, and the two concepts are synonymous ...
A bit array is a mapping from some domain (almost always a range of integers) to values in the set {0, 1}. The values can be interpreted as dark/light, absent/present, locked/unlocked, valid/invalid, et cetera. The point is that there are only two possible values, so they can be stored in one bit.
