What field uses =/= to mean !=?

[–] [email protected] 4 points 9 months ago (1 children)

!= isn't universal, i've mostly seen it used in programming.

Otherwise ≠ is the symbol we use in maths and generally the more common one.

=/= is just the worst rendition of ≠ for people that don't know how to write it or are too lazy to go find it.

Yeah =/= is honestly a little confusing. I know != isn't universal though, gotta start making sure to use ≠ instead

[–] [email protected] 1 points 9 months ago (1 children)

You're definite not wrong, I actually went to use "!=" first. But then thought if someone wasn't familiar with programming they might not get it, so I went with the "=/=" hoping it would make sense to more people. Forgot that we're on lemmy and the audience here would generally understand lol. Didn't know ≠ existed though, will probably use that from now on. Nice!

Have you heard of our Lord and Saviour, APL?

It's a shorthand way of writing ≠ digitally without needing to know the alt code or where it is in your mobile devices keyboard

[–] [email protected] 2 points 9 months ago* (last edited 9 months ago) (1 children)

Yeah in programming we just use !=:

!: NOT

=: EQUAL

It is not a composite expression but a single expression made up from 2 letters. And this is not a widespread notation.
