Subject: [PATCH] Source/JavaScriptCore/wasm/generateWasm.py: return value in
int for memorybits
https://bugs.webkit.org/show_bug.cgi?id=266942
Reviewed by Justin Michaud.
The assert function currently checks, if power number raised to the
number fits memorybits. This seems not always work on every system,
as it happens, that the float numbers are not correctly rounded.
This patch adds an int, so its being rounded to a full number and works
on my system, where otherwise the rounding would fail. The return method
also returns the result as an int.
Example:
import math
2 ** 3
= 8
2.0 ** 3.0
= 7.999999999999999
int(2.0) ** int(3.0)
= 8
2 ** int(3.0)
= 8
