It's not unusual to have bool to be the size of int for performance purposes. If for specific purposes (say hardware simulation) you need a type with N bits, you can find a library for that (e.g. GBL library has BitSet class).

WebFloating-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. The data model used when executing your program is the native data model associated with the active operating system kernel.
