data FractionalLit

Fractional Literal

Used (instead of Rational) to represent exactly the floating point literal that we encountered in the user's source program. This allows us to pretty-print exactly what the user wrote, which is important e.g. for floating point numbers that can't represented as Doubles (we used to via Double for pretty-printing). See also #2245. Note [FractionalLit representation] in GHC.HsToCore.Match.Literal The actual value then is: sign * fl_signi * (fl_exp_base^fl_exp) where sign = if fl_neg then (-1) else 1

For example FL { fl_neg = True, fl_signi = 5.3, fl_exp = 4, fl_exp_base = Base10 } denotes -5300
