ELI5:Is a irrational decimal number also irrational in a different base numbering system?
gpt
Provided that the other base is an integer base, yes (it is possible, with some modifications, to work in 'base pi', but in base pi, we write pi as just 1.0 [ed: 10, not 1]). A number is rational if and only if it can be written as a fraction with integer top and bottom, which doesn't depend on base.
