Can't pass negative float as CLI argument

[wdv4758h]

Describe the bug

See more info in discussion link.

Discussed in #12473

^{Originally posted by wdv4758h April 11, 2024}
This works:

# tmp.nu
def main [value: int] {
  print $value
}

nu tmp.nu -1

---

This does not work:

# tmp.nu
def main [value: float] {
  print $value
}

nu tmp.nu -1.0

Error: nu::parser::unknown_flag

  × The `main` command doesn't have flag `-1`.
   ╭─[<commandline>:1:7]
 1 │ main -1.0
   ·       ┬
   ·       ╰── unknown flag
   ╰────

---

Having a .nu script file, and call that script with arguments. Not the case defining function in current nushell and call it.
For some reasons, int argument is ok, but float argument is not.

How to reproduce

Write a nu script file with float as argument. Call it from CLI with negative float arguments.

Expected behavior

Have a good way to pass negative float from CLI, like int.

I've noticed that you can still pass a negative value if you put it in parentheses, but only if the command has been added to nu with def or use:

# tmp.nu
export def main [value: float] {
  print $value
}

> nu tmp.nu (-1.5)
Error: nu::parser::unknown_flag

  × The `main` command doesn't have flag `-1`.
