What is the float data type primarily used for?

The float data type is primarily used for storing numbers that require a decimal point. This is particularly important in various applications where precision and the ability to represent fractional values are necessary, such as in scientific calculations, statistical data analysis, and financial computations.

When using the float data type, it allows for the representation of real numbers, which include both the integer part and the fractional part, facilitating more accurate representations of continuous quantities. This contrasts with integer types, which can only represent whole numbers, and other data types that serve different purposes, such as text or binary objects. Understanding the float data type is crucial in database design and management as it informs how data will be stored, processed, and retrieved in GIS applications and other related fields.
