FileCheck does not work here because it can't capture floats and has no
tolerance operator for the float value.
To address the fragile parts of the test, I dropped the `sscanf` for a regex +
`getAsDouble`/`getAsInteger`, which also makes the category name part of the
match instead of a suffix check.
