What does the integer data type typically not allow?

The integer data type is designed specifically for whole numbers, which means it does not accommodate decimal numbers. Integers encompass both positive and negative values but do not support fractional components; this is a fundamental characteristic of how integers are defined in programming and computer science. Therefore, when working with integer types in data structures, calculations, or programming, you can only store whole numbers, ensuring that any value that includes a decimal is automatically rejected or leads to a type error.

The choices regarding storing negative numbers, whole numbers, and large values are all valid within the constraints of the integer data type, as integers can include both negatives and substantial magnitudes (limited primarily by the specific implementation or programming language limits).
