Hello APLers, Does 10○X and |X evaluate the expression in the same way? or is there a difference between how they evaluate the magnitude of a complex number (X here)

They are exactly the same.

Same for ¯10○X vs +X and ¯9○X vs ⊢Y

Interesting that the primitives tht have circle equivalents form a progression: + 4 bars from the centre, ⊢ three bars from the centre, | two bars from the centre.

Okay!

So does the 10○ representation use the | implementation under the hood?

Also, is there any specific reason why there are multiple ways of doing the same thing?

@Adám ahaha yeah, it is definitely meme-able content

@sloorush probably due to wanting 10 alongside others (for example ¯10 10 ○3j4)

@Silas Okay! general convenience thing

@sloorush Yeah, completeness in the functionality related to complex numbers.

@JoshuaEckroth Hi there. Interested in APL?
