Mathematical functions in Swift
...re currently available on Float and Double and it should be easy enough to convert to a CGFloat for example.
Instead of sqrt() there's the squareRoot() method on the FloatingPoint protocol. Again, both Float and Double conform to the FloatingPoint protocol:
let x = 4.0
let y = x.squareRoot()

SQL how to make null values come last when sorting ascending
...using the method for ints above:
SELECT *
FROM Employees
ORDER BY ISNULL(CONVERT(INT, HireDate)*0, 1), HireDate
(Lets pretend the schema has HireDate.)
These methods avoid the issue of having to come up with or manage a "maximum" value of every type or fix queries if the data type (and the maxi...
input() error - NameError: name '…' is not defined
...ike this
input_variable = raw_input("Enter your name: ")
If you need to convert the result to some other type, then you can use appropriate functions to convert the string returned by raw_input. For example, to read inputs as integers, use the int function, like shown in this answer.
