Topic: Function gives the list [0,1,2,...,n]

Yiming Xu (Feb 04 2025 at 19:00):

Is there a function that takes n and gives the list [0,...,n]? find_consts does not give me anything.

upt

Mathias Fleury (Feb 04 2025 at 20:00):

Better known under its notation:
term ‹[0..<3]›

Yiming Xu (Feb 04 2025 at 20:02):

It does not seem to be of the right type:
List.upt :: "nat ⇒ nat ⇒ nat list"

Yiming Xu (Feb 04 2025 at 20:02):

Is there another upt?

Yiming Xu (Feb 04 2025 at 20:03):

It should be nat => nat list I think

Yiming Xu (Feb 04 2025 at 20:04):

Ah I see, it takes the head and the last one.

Yiming Xu (Feb 04 2025 at 20:05):

Makes sense! Vielen Dank!

Only sets have this version (lessThan, {..<4})

Yiming Xu (Feb 04 2025 at 20:16):

I see. That's nice to know.
