Positive exponent sign in roundtrip

[emilk]

roundtrip27.json is [1.7976931348623157e308], but I feel [1.7976931348623157e+308] should be equally correct output as JSON allows (but does not mandate) a positive exponent sign.

Yes. Roundtirp tests are not required by JSON standard.
For example, 1 can be stringified as +1, 1.0, 1.00, 1e0, 1e-0, 1e+0, etc.
But often JSON generators will produce shortest output which can be sufficiently restored to the original data.

Brevity makes sense, but some other roundtrip tests are not briefest possible, like [0.0] (roundtrip20.json) which shortest form is [0]. So I guess the goal of these test are then "shortest form that restores data and type (int vs float)". That's fine, I just wanted to wrap my head around the rationale =)
