Combined from primary sources listed below.
See primary docmentation in context for method Int.
method Int(IO::Path:D: --> Int:D)
Coerces .basename to Int. Fails with X::Str::Numeric if base name is not numerical.
See primary docmentation in context for method Int.
method Int(Match:D: --> Int:D)
Tries to convert stringified result of the matched text into Int.
say ('12345' ~~ /234/).Int; # OUTPUT: «234»
say ('12345' ~~ /234/).Int.^name; # OUTPUT: «Int»
# the next line produces a warning about using Nil (result of a no match) in numeric context
say ('one-two' ~~ /234/).Int; # OUTPUT: «0» # because Nil.Int returns 0
See primary docmentation in context for method Int.
method Int(Map:D: --> Int:D)
Returns the number of pairs stored in the Map (same as .elems).
my $m = Map.new('a' => 2, 'b' => 17);
say $m.Int; # OUTPUT: «2»
See primary docmentation in context for method Int.
method Int(Rational:D: --> Int:D)
Coerces the invocant to Int by truncating non-whole portion of the represented number, if any. If the denominator is zero, will fail with X::Numeric::DivideByZero.
See primary docmentation in context for method Int.
method Int(Str:D: --> Int:D)
Coerces the string to Int, using the same rules as Str.Numeric.
See primary docmentation in context for method Int.
method Int(Num:D:)
Converts the number to an Int. Fails with X::Numeric::CannotConvert if the invocant is a NaN or Inf/-Inf. No rounding is performed.
See primary docmentation in context for method Int.
multi method Int(Date:D: --> Int:D)
Converts the invocant to Int. The same value can be obtained with the daycount method.
Available as of release 2023.02 of the Rakudo compiler.
See primary docmentation in context for method Int.
multi method Int(StrDistance:D:)
Returns the distance between the string before and after the transformation.
See primary docmentation in context for method Int.
multi method Int()
Coerces the invocant to a Numeric and calls its .Int method. Fails if the coercion to a Numeric cannot be done.
say 1+0i.Int; # OUTPUT: «1»
say <2e1>.Int; # OUTPUT: «20»
say 1.3.Int; # OUTPUT: «1»
say (-4/3).Int; # OUTPUT: «-1»
say "foo".Int.^name; # OUTPUT: «Failure»
See primary docmentation in context for routine Int.
multi method Int(Bool:D --> Int:D)
Returns the value part of the enum pair.
say False.Int; # OUTPUT: «0»
say True.Int; # OUTPUT: «1»
See primary docmentation in context for method Int.
multi method Int(::?CLASS:D:)
Takes a value of an enum and returns it after coercion to Int:
enum Numbers ( cool => '42', almost-pi => '3.14', sqrt-n-one => 'i' );
say cool.Int; # OUTPUT: «42»
say almost-pi.Int; # OUTPUT: «3»
try say sqrt-n-one.Int;
say $!.message if $!; # OUTPUT: «Cannot convert 0+1i to Int: imaginary part not zero»
Note that if the value cannot be coerced to Int, an exception will be thrown.
See primary docmentation in context for method Int.
method Int(List:D: --> Int:D)
Returns the number of elements in the list (same as .elems).
say (1,2,3,4,5).Int; # OUTPUT: «5»
See primary docmentation in context for method Int.
See primary docmentation in context for method Int.
method Int(Real:D:)
Calls the Bridge method on the invocant and then the Int method on its return value.
