What steps will reproduce the bug?
require("node:fs").writeFileSync(-0, "")
or
require("node:fs").appendFileSync(-0, "")
How often does it reproduce? Is there a required condition?
it always happens on my machine. i have not tried on any other computer or os
What is the expected behavior? Why is that the expected behavior?
for it to do the same thing as positive zero i assume
What do you see instead?
