The actions of type conversion in Eiffel, specifically converts to and converts from are defined as: A type based on a class CU converts to a type T based on a class CT (and T converts from U) if either CT has a conversion procedure using U as a conversion type, or CU has a conversion query listing T as a conversion type
Single precision is termed REAL in Fortran; [1] SINGLE-FLOAT in Common Lisp; [2] float in C, C++, C# and Java; [3] Float in Haskell [4] and Swift; [5] and Single in Object Pascal , Visual Basic, and MATLAB. However, float in Python, Ruby, PHP, and OCaml and single in versions of Octave before 3.2 refer to double-precision numbers.
User-defined data types are non-primitive types. For example, Java's numeric types are primitive, while classes are user-defined. A value of an atomic type is a single data item that cannot be broken into component parts. A value of a composite type or aggregate type is a collection of data items that can be accessed individually. [6]
Custom range types can be created to make new types of ranges available, such as IP address ranges using the inet type as a base, or float ranges using the float data type as a base. Range types support inclusive and exclusive range boundaries using the [] and () characters respectively.
Some IBM systems and SQL systems support DECFLOAT format with at least the two larger formats. [3] ABAP's new DECFLOAT data type includes decimal64 (as DECFLOAT16) and decimal128 (as DECFLOAT34) formats. [4] PL/I natively supports both fixed-point and floating-point decimal data.
Be aware that the bit numbering used here for e.g. b 9 … b 0 is in opposite direction than that used in the paper for the IEEE 754 standard b 0 … b 9, add. the decimal digits are numbered 0-base here while in opposite direction and 1-based in the IEEE 754 paper. The bits on white background are not counting for the value, but signal how to ...
