In Str§
See primary documentation in context for method Int
method Int(Str: --> Int)
Coerces the string to Int
, using the same rules as Str.Numeric
.
In role Rational§
See primary documentation in context for method Int
method Int(Rational: --> Int)
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
.
In role Enumeration§
See primary documentation in context for method Int
multi method Int(::?CLASS:)
Takes a value of an enum and returns it after coercion to Int
:
( 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.
In Num§
See primary documentation in context for method Int
method Int(Num:)
Converts the number to an Int
. Fails with X::Numeric::CannotConvert
if the invocant is a NaN
or Inf
/-Inf
. No rounding is performed.
In Cool§
See primary documentation 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»
In List§
See primary documentation in context for method Int
method Int(List: --> Int)
Returns the number of elements in the list (same as .elems
).
say (1,2,3,4,5).Int; # OUTPUT: «5»
In Map§
See primary documentation in context for method Int
method Int(Map: --> Int)
Returns the number of pairs stored in the Map
(same as .elems
).
my = Map.new('a' => 2, 'b' => 17);say .Int; # OUTPUT: «2»
In Match§
See primary documentation in context for method Int
method Int(Match: --> Int)
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 contextsay ('one-two' ~~ /234/).Int; # OUTPUT: «0» # because Nil.Int returns 0
In Date§
See primary documentation in context for method Int
multi method Int(Date: --> Int)
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.
In enum Bool§
See primary documentation in context for routine Int
multi method Int(Bool --> Int)
Returns the value part of the enum
pair.
say False.Int; # OUTPUT: «0»say True.Int; # OUTPUT: «1»
In role Real§
See primary documentation in context for method Int
method Int(Real:)
Calls the Bridge
method on the invocant and then the Int
method on its return value.
In StrDistance§
See primary documentation in context for method Int
multi method Int(StrDistance:)
Returns the distance between the string before and after the transformation.
In IO::Path§
See primary documentation in context for method Int
method Int(IO::Path: --> Int)
Coerces .basename
to Int
. Fails with X::Str::Numeric
if base name is not numerical.
In IntStr§
See primary documentation in context for method Int
method Int
Returns the integer value of the IntStr
.
