DoubleToLongFunction represents a function that accepts a double-valued argument and produces a long-valued result. This is the double-to-long primitive specialization for Function.
The following example shows how to use DoubleToLongFunction
.
import java.util.function.DoubleToLongFunction; public class Main { public static void main(String[] args) { DoubleToLongFunction dl = (x) -> {return Long.MAX_VALUE - (long)x;}; System.out.println(dl.applyAsLong(3.14)); } }
The code above generates the following result.
