A FatRat
is a rational number stored with arbitrary size numerator and denominator. Arithmetic operations involving a FatRat
and optionally Int
or Rat
objects return a FatRat
, avoiding loss of precision.
Since, unlike Rat
, FatRat arithmetics do not fall back Num
at some point, there is a risk that repeated arithmetic operations generate pathologically large numerators and denominators.
There are two common ways to generate FatRat
objects: through the FatRat.new(Int, Int)
constructor, which generates them from numerator and denominator, or by calling the .FatRat
method on an Int
or Rat
object.
Methods§
method raku§
multi method raku(FatRat: --> Str)
Returns an implementation-specific string that produces an equivalent object when given to EVAL.
say FatRat.new(1, 2).raku; # OUTPUT: «FatRat.new(1, 2)»
