FatRat Reference

Rational number (arbitrary-precision)

What it is #

Routines #

Signatures are reproduced from the documentation, including their declared return types. A routine listed here is part of the type's published interface; whether Raku++ implements it is a separate question, answered by the examples below.

method raku #

multi method raku(FatRat:D: --> Str:D)

Returns Str:D.

Returns an implementation-specific string that produces an equivalent object when given to EVAL.

Examples, run three ways #

Every example below comes from the official documentation, together with the output that documentation asserts. Each was then executed by Rakudo and by Raku++ when this page was built. Where the three agree, one result is shown; where they do not, all three are — because which of them is wrong is exactly the information worth having.

class FatRat is Cool does Rational[Int, Int] {}

Not executed: the documentation states no expected output for this example.

say FatRat.new(1, 2).raku; # OUTPUT: «FatRat.new(1, 2)␤»
Output
FatRat.new(1, 2)

Documentation, Rakudo and Raku++ all agree.
