Swift: How to Round Up a CGFloat - Quick and Easy Tips

If you're working with floating-point numbers in Swift, you may find yourself needing to round up a CGFloat value at some point. Luckily, Swift provides a quick and easy way to do this using the ceil() function.

To round up a CGFloat value, simply call the ceil() function and pass in the CGFloat value you want to round up as an argument. The ceil() function will return the smallest integer value that is greater than or equal to the input value.

Here's an example of how to use the ceil() function to round up a CGFloat value:

let myFloat: CGFloat = 3.14159
let roundedUpFloat = ceil(myFloat)
print(roundedUpFloat) // Output: 4.0

In the example above, we define a CGFloat variable called myFloat and assign it a value of 3.14159. We then call the ceil() function and pass in myFloat as an argument. The function returns a value of 4.0, which we assign to the variable roundedUpFloat.

That's all there is to it! With the ceil() function, rounding up a CGFloat value in Swift is quick and easy.
