nen<p>I found the culprit: if x is a Float32, then the reassignment `x = x % 1.0` changes its type to Float64 (the type of `1.0`), but if x is Vector{Float32}, reassigning an element with `x[i] = x[i] % 1.0` won't change the type of the vector x.</p><p>The sneaky type bug could have been avoided by writing two lines instead of one, replacing the `% 1.0` with `trunc()`:</p><p>x = (x + c)<br>x -= trunc(x)</p><p>This also runs more than 3 times as fast as the modulus, even with the correct divisor `1.0f0`.</p><p><a href="https://mementomori.social/tags/JuliaLang" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>JuliaLang</span></a></p>

Lee Phillips<p>If you want to get a good foundation in Julia, spend some quality time with a book.

I brought together the JuliaCtags <a href="https://fediscience.org/tags/JuliaLang" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>JuliaLang</span></a> package to generate a `ctags` file suitable for use by `exuberant-ctags` on Linux (at least). I used this to generate tags for my various projects both individually and all together as well as tags for the full Julia base module. This was then followed by the configuration of `tags-table-list` [*] in <a href="https://fediscience.org/tags/Emacs" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Emacs</span></a> to work with multiple tags files.</p><p>The results is that the various Emacs <a href="https://fediscience.org/tags/xref" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>xref</span></a> commands work very well for navigating in the code: jump to definitions, find all references, go back and forth, etc.</p><p>[*] the use of a table of tags files is quite important when working with multiple inter-linked packages. I hadn't known about this variable before as I somehow missed the relevant paragraph in the documentation the various times I'd checked previously. :-(</p>
