I don’t see that: julia> BigFloat(1.0) |> typeof BigFloat

  The problem isn't the type, it's the bits. If you convert from Float64, you'll get garbage bits once you go past the bits determined by float64: julia> BigFloat(1.1) 1.100000000000000088817841970012523233890533447265625 I'd recommend using the big string macro though isntead of converting explictly from a string: julia> big"1.1" 1.100000000000000000000000000000000000000000000000000000000000000000000000000003

    Oh, I see. Thank you. (And, in Julia’s defense, this is all spelled out in the documentation, immediately accessible from the REPL. I just never read it carefully enough.)

My concern is most physicists won't read that either and may not even notice the loss of precision until it's too late (after a paper has been published).
