Swift - ceil() Function
The Swift ceil() function returns the next highest integer value by rounding up the specified number, if necessary. In other words, it rounds the fraction UP of the given number.
Syntax
In Foundation framework, it is defined as follows:
public func ceil(_ x: CGFloat) -> CGFloat public func ceil(_ x: Float) -> Float public func ceil(_ x: Float80) -> Float80 public func ceil(_ __x: Double) -> Double
Parameters
x |
Specify a number. |
Return Value
Returns the next highest integer value by rounding UP the specified number, if necessary.
Example:
In the example below, ceil() function is used to round the fraction UP of the specified number.
import Foundation
print("ceil(-10.2) = \(ceil(-10.2))")
print("ceil(-10.8) = \(ceil(-10.8))")
print("ceil(5.2) = \(ceil(5.2))")
print("ceil(5.8) = \(ceil(5.8))")
The output of the above code will be:
ceil(-10.2) = -10.0 ceil(-10.8) = -10.0 ceil(5.2) = 6.0 ceil(5.8) = 6.0
