WebA bit array (also known as bitmask, [1] bit map, bit set, bit string, or bit vector) is an array data structure that compactly stores bits. It can be used to implement a simple set data structure. A bit array is effective at exploiting bit-level parallelism in hardware to perform operations quickly. WebArithmetic may only be performed on integers in D programs. Floating-point constants may be used to initialize data structures, but floating-point arithmetic is not permitted in D. D provides a 32-bit and 64-bit data model for use in writing programs.
