      When entering a number as input for Fluent the number of digits is not limited. But when checking the value again in the graphical or text user interfaces (GUI or TUI) the number of digits is limited. Internally, Fluent uses the provided digits up to machine accuracy. This accuracy depends on single or double precision, the operating system and the used hardware. But some input field do not show all digits that are used internally.
