I’m a pretty new user to Julia, and I usually google how to do things in Julia. The problem is that most of google answers are several versions old that uses functions that are deprecated and removed.

For example I search on google

> julia floating point binary representation

and one of the answers suggested me to use `num2hex`, and when I tried it there is UndefVarError, and more googling shows that `num2hex` is deprecated without any clear replacement function. Fortunately when I google it again now the first results shows that I can use `bitstring` function, but then there are more functions that are removed, such as `linspace`.

Is there a page where it lists removed functions and suggest alternatives?

Welcome to the Julia’s Discourse!

Concerning your question, Julia 0.7 was a transitory release, with all the deprecation announcements, here are the list of deprecated functions and alternatives:  
[https://docs.julialang.org/en/v0.7/NEWS/#Deprecated-or-removed-1](https://docs.julialang.org/en/v0.7/NEWS/#Deprecated-or-removed-1)  
in particular, `num2hex(2.2)` is replaced by `reinterpret(UInt64, 2.2)`
