From 0d5196feadafa77c727f517d747ffcf3fd0e8ba9 Mon Sep 17 00:00:00 2001

Subject: [PATCH] round result of (highest as f64).log(2.0)
Even though (1024f64).log(2.0) has an exact, representable, value, with
rustc 1.32 on i386 it comes out as +9.999999999999999985 with
optimization enabled. And the rustc doesn't like having two defintions
for U1024 etc.
