eqv is an operator that tests the two operands for equivalence. It returns the True value if the operands are of the same type and contain the same values.
my $x = 3; my $y = 3; say $x eqv $y; # True
An example with a bit more complex data structures:
my @a = (3, 4); my @b = (3, 4, 5); @b.pop; say @a eqv @b; # True
Note that because the integer and the floating-point types are different data types, comparing two equal numbers may give a False result. The same applies to the comparison with a string containing a numeric value.
say 42 eqv 42.0; # False say 42 eqv "42"; # False
It is even trickier when one of the operands is of the Rat value.
say 42 eqv 84/2; # False, 84/2 is Rat say 42 eqv (84/2).Int; # True, the value is cast to Int
