What does "floating" mean in it?

Floating in IT, or Information Technology, has several specific technical meanings that are different from everyday use. The most common is floating point, often abbreviated as float, which is a type of number representation in programming that includes decimal points, like 3.14 or 0.001, as opposed to integers. Floating point arithmetic is how computers handle very large or very small fractional numbers. Another meaning is floating IP address or floating license, which means an IP or license that is not tied to a single machine but can move or be reassigned dynamically between servers as needed for load balancing or failover. In networking, a floating network or floating VLAN means a virtual network that is not physically fixed. In user interface design, a floating window, floating toolbar, or floating action button is an element that hovers above the main content and stays visible while you scroll. In web development, float is a CSS property that lets an element float to the left or right, allowing text to wrap around it. In all IT contexts, floating implies not fixed, movable, or dynamically assigned.
