# rounded(_:) Returns this value rounded to an integral value using the specified rounding rule. ``` func rounded(_ rule: FloatingPointRoundingRule) -> Self ``` ## Parameters `rule` The rounding rule to use. ## Return Value The integral value found by rounding using `rule`. ## Discussion The following example rounds a value using four different rounding rules: ``` let x = 6.5 // Equivalent to the C 'round' function: print(x.rounded(.toNearestOrAwayFromZero)) // Prints "7.0" // Equivalent to the C 'trunc' function: print(x.rounded(.towardZero)) // Prints "6.0" // Equivalent to the C 'ceil' function: print(x.rounded(.up)) // Prints "7.0" // Equivalent to the C 'floor' function: print(x.rounded(.down)) // Prints "6.0" ``` For more information about the available rounding rules, see the `FloatingPointRoundingRule` enumeration. To round a value using the default “schoolbook rounding” of `.toNearestOrAwayFromZero`, you can use the shorter `rounded()` method instead. ``` print(x.rounded()) // Prints "7.0" ``` --- Copyright © 2026 Apple Inc.
