Hello! This page is located in the "Experimental" section: https://www.scala-lang.org/api/3.x/docs/docs/reference/experimental/numeric-literals.html However, as it seems, the "Meaning of Numeric Literals" part is non-experimental and is actual in Scala 3 by default. I suppose the page should be reviewed and part of it should be moved to: https://www.scala-lang.org/api/3.x/docs/docs/reference/changed-features/numeric-literals.html?
