+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
