So called “dependent type”? 16What are types used for in programming? 17What are types used for in programming? • Similar to money and its roles: • Medium of exchange

Back to Basics: Algebraic Data Types I also do C++ training! arthur.j.odwyer@gmail.com Arthur O’Dwyer 2020-09-16Outline ● Why the name “algebraic data types”? [3–18] ○ Memory layout diagrams. Why Questions? ● More about pair and tuple [57–69] Questions? 2What do I mean by algebraic types? pair C++98. The original algebraic data type. tuple C++11. optional C++17. variant tuple are product types To find the size of the domain of a pair or tuple type, we take the product of the sizes of its element types. Therefore pair and tuple are known as product types. 5 A A possible

std::simd how to express inherent parallelism efficiently via data-parallel types Dr. Matthias Kretz GSI Helmholtz Center for Heavy Ion Research CppCon ’23 @mkretz@floss.social github.com/mattkretzMotivation ResearchMotivation std::simd Overview Example: Image Processing Programming Models Outlook Summary Data-Parallel Types One variable stores WT values. One operator signifies WT operations (element-wise). W for “width”; vectorizable type — all arithmetic types except bool or long double • simd_mask behaves like bool (element-wise) In contrast to bool, there are many different mask types: • storage: bit-masks vs. element-sized

Your first step to learn TypeScript The Basics Step one in learning TypeScript: The basic types. Everyday Types The language primitives. Narrowing Understand how TypeScript uses JavaScript knowledge to Object Types How TypeScript describes the shapes of JavaScript objects. Creating Types from Types An overview of the ways in which you can create more types from existing types. Generics Types which take Indexed Access Types Using Type['a'] syntax to access a subset of a type. Conditional Types Create types which act like if statements in the type system.

[https://peps.python.org/pep-0484/]) to your Python programs, and mypy will warn you when you use those types incorrectly. Python is a dynamic language, so usually you’ll only see errors in your code when you input("What is your favourite number?") print("It is", number + 1) # error: Unsupported operand types for + ("str" and "int") Adding type hints for mypy does not interfere with the way your program easy-to-use type system, supporting features such as type inference, generics, callable types, tuple types, union types, structural subtyping and more. Using mypy will make your programs easier to understand
