Changes for version 2.04
- No change to what the module computes. Fixes t/JQ-XS.t on a perl built with -Duselongdouble or -Dusequadmath, where it failed:
- Failed test 'float identity roundtrip'
- at t/JQ-XS.t line 44.
- $got->[0] = '3.14000000000000012'
- $expected->[0] = '3.14'
- jq holds every number as an IEEE double. An NV on those perls is wider than that, so the literal 3.14 loses the excess precision on the way into jq and comes back as the nearest double, which is correct but does not compare equal to what went in. The test now narrows the literal with "pack 'd'" first -- the same conversion the XS performs when it casts an NV to a double for jq, and a no-op where an NV already is one -- so both sides hold the same double on every perl. Documented under "Number handling", with the note that process_json() is unaffected: it returns jq's own JSON text, and jq reproduces the literal of any number it has not done arithmetic on. Reported by Andreas Koenig (GH #3).
