There is already a `big` macro: Float128(big"0.65848717272880453138501720234176360203750453725471077124688134") Instead of copying and pasting in the REPL, couldn't you write these numbers to a file and read them in as strings in Julia? There has been some discussion in the past about forwarding strings like this to the parser already wrapped in a macro (as is done for large integer values); I don't recall what the issue with this was.
