I am lost. What changed so the simple algebra like 2ˆ2 does not work anymore (Julia v1.6.3) in the REPL (on MacOS)? And how would I draw the power of a int or a float? I get julia> 2ˆ2 ERROR: UndefVarError: ˆ2 not defined Stacktrace: [1] top-level scope @ REPL[31]:1 And julia> 2 ˆ 2 ERROR:…

You are using “Modifier Letter Circumflex Accent” with code julia> Char('ˆ') 'ˆ': Unicode U+02C6 (category Lm: Letter, modifier) You need CIRCUMFLEX ACCENT julia> Char('^') '^': ASCII/Unicode U+005E (category Sk: Symbol, modifier) (edited: using Char instead of UInt16, :+1: to @Palli )

You have probably copy/pasted the ˆ from somewhere, try this one: 2^2 or the single ^. Copy/paste one of my suggestions.

It still may be a MacOS thing, so someone with that system may know better…

Phenomenal! It just had to be something like this. In fact, I am new to the Mac-keyboard and it is these small things that make doubt this path.

[image] met-j: and it is these small things that make doubt this path. Well, this can happen in every system,e.g. R REPL just the same: > 2**2 [1] 4 > 2^2 [1] 4 > 2ˆ2 Fehler: unerwartete Eingabe in "2ˆ" No doubts appropriate! Instead, delight is today’s feeling! :wink:

Or Python >>> 2**2 4 >>> 2^2 0 >>> 2ˆ2 File "<stdin>", line 1 2ˆ2 ^ SyntaxError: invalid syntax

[image] met-j: I am new to this system and it is these small things that make doubt this path. I’m conflicted here. With the correct ASCII operator ^ this works, but Julia does provide Unicode options in many cases, and could also support ˆ “Modifier Letter Circumflex Accent” for this. I’m no…

My main struggle is actually the MacBook keyboard where the ASCI tilde and ^ are hidden from simple key strokes. My left pinky is just getting board while the others are starting emacs like yoga exercises without any emacs in sight.

If it’s not on the keyboard that seems like an argument for some workaround… If Julia does it allowing the other ˆ it makes for some slight visual distinction in code bases, why I’m conflicted. It’s most likely also a technical breaking change. Maybe there’s some editor support available that maps i…

Resolved the twist! My keyboard was set to en-US international instead of just en-US. https://apple.stackexchange.com/questions/234352/how-do-i-input-instead-of-ˆ

By the way, it’s quite easy to add your own REPL shortcuts, if there’s a particular character you need to type which isn’t in the REPL’s built-in tab completion dictionary: For example, to have \power expand to ^: using REPL REPL.REPLCompletions.latex_symbols["\\power"] = "\u005e" [completions-1] …
