WebMar 31, 2024 · The IEEE standard floating point types currently supported by D are float and double. Additionally, D supports the real type, which is either 'IEEE 80-bit extended' if supported by the CPU; otherwise, it is the same as double. In the future, the new types from 754-2008 will be added: quadruple, decimal64, and decimal128.

By their nature, all numbers expressed in floating-point format are rational numbers with a terminating expansion in the relevant base (for example, a terminating decimal expansion in base-10, or a terminating binary expansion in base-2). Irrational numbers, such as π or √2, or non-terminating rational numbers, must be approximated. The number of digits (or bits) of precision also limits the set of rational numbers that can be represented exactly. For example, the decima…
