Aren't these wrong? e.g. I think we'll get
expect_snapshot_failure(expect_gt(x, 1.0 * x))
`x` is not strictly greater than 1.0 * x.
0.0000100 - 0.0000110 = 0 < 0
The negated open interval is a closed interval, and vice versa.
(even if I'm reading it wrong we'll still want a test of the edge case)

Also that revealed a bug when the number of digits in the difference is much smaller than the values.

Fixes #2006
@MichaelChirico could you please take a look? This doesn't need to be perfect, but is hopefully better than the current display.
