Lesson 04 - Float
A float is a data type that represents decimal numbers or real numbers. Floats are used to store and manipulate numerical values with fractional parts. They are characterized by their ability to hold both integer and fractional components, making them suitable for a wide range of mathematical calculations.
The float() is a built-in function used to convert a variable or object into its floating-point representation. It accepts various data types, including integers and strings, and returns a floating-point number. This function is crucial for handling decimal values, facilitating arithmetic operations with more precision.
The int() is a built-in function used to convert a variable or object into its integer representation. It accepts various data types, including floats and strings, and returns the truncated integer value. This function is essential for converting numeric values to integers, facilitating mathematical operations that require whole numbers. When applied to strings, int() interprets the string's contents as an integer if it represents a valid integer literal.
