SPVM::Comparator::Double - Comparator::Double in SPVM | a callback interface for double comparation
use Comparator::Double; my $comparator : Comparator::Double = method : int ($a : double, $b : double); { return $a <=> $b; }; my $result = $comparator->(3, 5);
Comparator::Double is a callback interface to compare two double values.
method : int ($a : double, $b : double);
This method must receive two numbers and return 1 if $a is more than $b, -1 if $x is less than $b, 0 if $a equals $b in the implementation.
This method is planned to be implemented in other classes.
