Documentation for routine max assembled from the following types:

language documentation Operators

From Operators

(Operators) infix max

Returns the largest of the arguments, as determined by cmp semantics.

my $foo = -42;
$foo max= 0   # read as: $foo increases to 0

class Range

From Range

(Range) method max

method max(Range:D:)

Returns the end point of the range.

say (1..5).max;                                   # OUTPUT: «5␤» 
say (1^..^5).max;                                 # OUTPUT: «5␤»

class Supply

From Supply

(Supply) method max

method max(Supply:D: &custom-routine-to-use = &infix:<cmp> --> Supply:D)

Creates a supply that only emits values from the given supply if they are larger than any value seen before. In other words, from a continuously ascending supply it will emit all the values. From a continuously descending supply it will only emit the first value. The optional parameter specifies the comparator, just as with Any.max.

class Any

From Any

(Any) method max

Defined as:

multi method max()
multi method max(&by)
multi sub max(+args, :&by!)
multi sub max(+args)

Coerces the invocant to Iterable and returns the numerically largest element; in the case of Hashes, the Pair with the highest value.

If a Callable positional argument is provided, each value is passed into the filter, and the return value is compared instead of the original value. The original value is still the one returned from max.

say (1,7,3).max();                # OUTPUT:«7␤» 
say (1,7,3).max({1/$_});          # OUTPUT:«1␤» 
say max(1,7,3,:by( { 1/$_ } ));   # OUTPUT: «1␤» 
say max(1,7,3);                   # OUTPUT: «7␤» 
max( %(a => 'B', b=> 'C' ) ).say; # OUTPUT: «b => C␤»
