Final answer:
All numbers in TypeScript are either floating point values or integers. JavaScript uses a data type called 'number' to represent both types.
Step-by-step explanation:
All numbers in TypeScript are either floating point values or integers. JavaScript, the programming language that TypeScript is based on, uses a data type called 'number' to represent both floating point values (decimal numbers) and integers (whole numbers). For example, the number 3.14 and the number 7 are both considered 'number' data types in JavaScript.
