The *sign emote accepts any number outside its stated 0-10 range

BYOND Version

516.1669

Issue Description

The *help list states: "sign[-number(0-10)]", which implies that only numbers between 0 and 10 can be used. Instead, it accepts any kind of number, including numbers outside the 0-10 range.

What did you expect to happen?

I expected to only be able to use numbers between 0 and 10.

What happened instead?

I was able to use any number, including negative numbers and decimals, though I don't know if being able to use decimals is intended or not.

Why is this bad/What are the consequences?

The *help list shouldn't lie to the player.

Steps to reproduce the issue.

Say "*sign-#" where # is any number you want. Notice that you can sign numbers such as -100000 or 9999999999999.

When did the problem start happening?

I only used the sign emote for the first time today.

Extra information

The sign emote was re-added in #29872
