Swift provides several floating point data types, which are value types. These include:
Float: A single-precision, 32-bit floating point number.Double: A double-precision, 64-bit floating point number.
These types are part of Swift's fundamental data structures and are used to represent decimal numbers with varying degrees of precision.
