Deno.ppid returns bigint, although type declarations says it's number

[magurotuna]

Summary

Deno.ppid is supposed to have type of number (according to https://deno.land/[email protected]?s=Deno.ppid), but what we get actually is bigint.

What happens now

Version: Deno 1.40.2

$ deno eval "console.log(typeof Deno.ppid, Deno.ppid)"
bigint 89489n

$ deno --version
deno 1.40.2 (release, aarch64-apple-darwin)
v8 12.1.285.6
typescript 5.3.3

Expected result

typeof Deno.ppid === "number"

Additional note

• Deno.pid (not ppid) is of type number as expected.
• Deno.ppid is of type number if we run it in Deno Deploy.
