Hi guys, I’m still a beginner in Julia and I would like tips on how I can get greater precision in extensive mathematical calculations performed in Julia. Thanks 🙂

Here is something to get you started: [Integers and Floating-Point Numbers · The Julia Language](https://docs.julialang.org/en/v1/manual/integers-and-floating-point-numbers/#Arbitrary-Precision-Arithmetic-1)

And maybe another place to check out: [GitHub - JeffreySarnoff/ArbNumerics.jl: extended precision math, accurate and performant](https://github.com/JeffreySarnoff/ArbNumerics.jl)
