Precision String Format Specifier In Swift
...matting:
println(NSString(format:"%.2f", sqrt(2.0)))
Extrapolating from python, it seems like a reasonable syntax might be:
@infix func % (value:Double, format:String) -> String {
return NSString(format:format, value)
}
Which then allows you to use them as:
M_PI % "%5.3f" ...

return False
In the first example, x == 1 and y == 2. ...

How to define a function in ghci across multiple lines?
...
Setting multiline mode makes ghci behave much like the Python interpreter in this regard. Very convenient! You can in fact create a .ghci file in your home directory in which you put :set +m and multiline mode will become the default every time you start ghci!
