What are whole numbers commonly known as?

Whole numbers are commonly referred to as integers. Integers encompass all positive whole numbers, negative whole numbers, and zero, but they do not include fractions or decimals. This categorization makes integers integral to various mathematical operations and computing contexts, where whole number values are required.

Decimals and floats are types of numerical values that include fractions or can represent numbers with decimal points, which do not fit the definition of whole numbers. Strings refer to sequences of characters, typically used for text and cannot be classified as numbers. Hence, recognizing that whole numbers are a subset of integers clearly identifies why the correct option is integers.
