With all the other things moving out of Base, there are not really many places where BigFloat is used anymore: In int.jl, there is a parsing routine that would simply move to stdlib/BigFloat.jl mpfr.jl would move to stdlib/BigFloat.jl In printf.jl (which I’d thought had already moved to stdlib/Pr…

Maybe i don’t have the full picture, but it looked like stdlib is still a dependency (i.e. you don’t run julia without stdlib)?

I’d thought the whole point of moving things to stdlib was so that you could run julia without the parts you didn’t want, such as LinAlg, etc.

Unfortunately, we need big ints and big floats in the array hashing code to compute the difference between two subsequent elements in an array without any overflow or precision loss. That’s not great, but so far we haven’t found any other solution (see this PR ). This system could be easily disabled …

Where are they being used in the array hashing code? I’d looked for all methods using BigFloat, but must have missed some places then where they are being used. [image] nalimilan: Though we can avoid exporting them from Base and use a stdlib module for that instead. That’s my big issue, if …
