SPVM::C...:Double(3)

💖 Name 💖

Okay so welcome to SPVM::C...:Double(3), bestie — this page comes from the User Contributed Perl Documentation manual, and the main character is SPVM::Comparator::Double: the interface type for the double comparation callback. 💅

✨ Usage ✨

Here's the usage example, literally verbatim:

         use Comparator::Double;

         my $comparator = (Comparator::Double)method : int ($a : double, $b : double); {
           return $a <=> $b;
         };

         my $result = $comparator->(3, 5);

🦋 Description 🦋

Comparator::Double is the interface type for the double comparation callback. No cap, that's the whole vibe. 🫶

🌸 Interface Methods 🌸

The required method is exactly this signature:

required method : int ($a : double, $b : double);

This method must receive two values whose types are double, and it returns the following value:

• If the first argument is greater than the second argument, it returns 1. ✅
• If the first argument is lower than the second argument, it returns -1. 💀
• If the first argument is equal to the second argument, it returns 0. ✨
