23*21-/541-*+
rather than 23*21-/5+41-*?

FP (function programming): notation
The language used here is FP.
I don't understand the difference between the use of <> and [].
For example:
2 : <3,4,5> -> 4
But
+ o [1,2] : <2,3> -> 5
Why is the first sequence written with [] instead of <> ?
Thanks!

Is there a standard way to represent any API?

Large numbers/integers in dot notation
Any handy method to have for instance the number 1000000 become 1.000.000 and 10000 become 10.000 etc? I'm dealing with integers so comma's are not a necessity to include (but would be handy though, like 10.000,53).
Thanks in advance
