@bquorning Could you add a regression test that reproduces the issue? Thanks! |

Also, consistently render percentages without a space before it. To get some usable data for the test, I copied a number of files from SingleCov's spec/source_file_spec.rb.

When the coverage percentage is rounded up, people may end up misconfiguring SimpleCov with a number that 0.01 too high. They may even think they have a 100% converage, when in fact the coverage is only marginally higher than 99.995%. This commit changes all uses of `#round` for `#floor`, thus always rounding _down_ and never _up_.
I don't think it matters if it's rounded up or down. The point here is that we render it the same way in the header as we do in the table.

I didn’t find any existing tests in the repo, so I copied a handful of files from simplecov's spec suite to generate some usable coverage numbers to output. The test is currently very long and hard to read, but I’m ready to iterate on that. What is more concerning is that the tests are currently failing on Ruby 2.4 and 2.5. @amatsuda do you know if simplecov-html actually works with those Ruby versions and simplecov v0.18.5? |

This commit changes all uses of
#roundfor#floor, thus always rounding down and never up.Fixes #130.
May even fix simplecov-ruby/simplecov#948 too.
