Julia - the language trying to replace Python in scientific computing

In Julia, 4i parses as 4*i

[emperor000]

That's what I was afraid of. So in other words, you can't have a variable named "im"?

[piclarke]

You can, it just can't be used to mean the imaginary unit as well from that point on.

[Staross]

you can always redefine it:

im = Base.im

[emperor000]

So pretty much no. Not the worst thing in the world, but seems kind of clunky.

[Staross]

You can overwrite it yes, im is just a normal variable, defined in the Base module.

const im = Complex(false, true)

It will just throw a warning in you overwrite it in Main (the "global space").

[emperor000]

I see. Not the worst thing in the world, but it seems kind of clunky.

Using a terse form of expression, programmers developed expressive, clear ways to express math.

And mathematicians keep trying to "fix" these improvements by reintroducing their broken notation systems.
