What does a real or floating-point data type represent?

Only whole numbers
Numbers with decimal points or fractions
Alphanumeric characters
Logical values like TRUE or FALSE

The correct answer is: Numbers with decimal points or fractions

A real or floating-point data type is specifically designed to represent numbers that include a fractional component, allowing for the storage of decimal values. This capability is essential for applications that require precision in calculations involving real-world measures, such as scientific computations, financial calculations, and graphics programming. This data type is distinct from others that may only accommodate whole numbers, thereby making it versatile for a broader range of numeric representations. Unlike types that represent alphanumeric characters or logical values, which have entirely different purposes, the floating-point type is tailored specifically for numerical data requiring precision and the ability to express values that are not just integers.
