Question: 1 / 400

num=8.0f is of what data type?

integer

float

The correct answer is that the data type of num=8.0f is a float. In programming, particularly within Unity and C#, the suffix 'f' denotes that the literal number is a float, which is a single-precision floating point. This means that the number can represent decimal values and has a wider range than an integer while also using less memory than a double, which is a double-precision floating point type.

The float data type is commonly used for representing numbers that require fractional parts, such as positions or velocities in game development. In contrast, an integer is a whole number without any decimal point, while double represents a floating-point number with double precision and takes up more memory. Lastly, a string represents a sequence of characters, and thus is not applicable in this case.

Understanding these distinctions helps clarify why num=8.0f specifically represents a float data type in Unity.
