# ...(_:) Returns a partial range extending upward from a lower bound. ``` static func ... (minimum: Self) -> PartialRangeFrom ``` ## Parameters `minimum` The lower bound for the range. ## Discussion Use the postfix range operator (postfix `...`) to create a partial range of any type that conforms to the `Comparable` protocol. This example creates a `PartialRangeFrom` instance that includes any value greater than or equal to `5.0`. ``` let atLeastFive = 5.0... atLeastFive.contains(4.0) // false atLeastFive.contains(5.0) // true atLeastFive.contains(6.0) // true ``` You can use this type of partial range of a collection’s indices to represent the range from the partial range’s lower bound up to the end of the collection. ``` let numbers = [10, 20, 30, 40, 50, 60, 70] print(numbers[3...]) // Prints "[40, 50, 60, 70]" ``` > Precondition: `minimum` must compare equal to itself (i.e. cannot be NaN). --- Copyright © 2026 Apple Inc.
