Which data type holds a floating point value such as 1.5 or 3.14?

• A. Decimal
• B. Double
• C. Integer
• D. float

Answer: (D)

Floating-point numbers are used when you need to store values with a fractional part, such as 1.5 or 3.14. An integer can’t represent decimals, so it’s not suitable here. Among the options, the type named float is the standard floating-point type used to store numbers with decimal parts. While another floating-point type like double can also hold these values, the question points to the common floating-point category, which is typically represented by float. The decimal type, on the other hand, is designed for fixed-point decimal arithmetic and high-precision monetary calculations, not general floating-point behavior. So, the best fit for storing a value with a fractional part like 1.5 or 3.14 is float.
