What data type allows for numbers with fractions, represented with decimal points?

The answer is correct because the float data type is specifically designed to represent numbers that include fractions, utilizing decimal points. In programming, float allows for a broader range of numerical values, accommodating both whole numbers and fractional numbers, such as 3.14 or -0.001. This is crucial for tasks requiring precision, such as calculations involving scientific data, financial transactions, or any situation where exact decimal representation is necessary.

Other data types serve different purposes. The integer type can only store whole numbers, with no ability to represent decimals or fractions. The char type is used for single characters, such as letters or symbols, and does not involve numerical representation at all. Meanwhile, the string type is designed for sequences of characters, which can represent text, but any numbers within them are treated as a string of characters rather than as numerical values for calculations. Thus, the float data type is the only one among the options that accurately meets the requirement of representing numbers with fractions.
