![]() Signed integer of size equal to a pointer The D compiler also provides the type aliases listed in the following table: Table 2–3 D Integer Type Aliases If no sign qualifier is present, the type is assumed to be signed. Integer types may be prefixed with the signed or unsigned qualifier. Integers are always represented in twos-complement form in the native byte-encoding order of your system. The names of the integer types and their sizes in each of the two data models are shown in the following table. You can determine the native data model for your system using isainfo -b. The data model used when executing your program is the native data model associated with the active operating system kernel. D provides a 32-bit and 64-bit data model for use in writing programs. Floating-point constants may be used to initialize data structures, but floating-point arithmetic is not permitted in D. ![]() Arithmetic may only be performed on integers in D programs. D provides fundamental data types for integers and floating-point constants.
