P in constant declaration

Question

public static final double MAX_VALUE = 0x1.fffffffffffffP+1023;
public stati         


        

Answer 1

The p syntax if used for defining a double literal in hex. This is useful when you want to define its exact representation but isn't useful in general code because you want the double to be a decimal value rather than some hex pattern.
