Why this ("Filter" in jqplay.org): {"key":633447818234478180}
returns this ("Result" in jqplay.org): {"key": 633447818234478200}
Original JSON doesn't matter.
Why is it changing 180 into 200? How can I overcome this? Is this a bug? A number too big?
回答1:
I believe this is because jq can only represent legal JSON data and the number you've given is outside the range that can be represented without loss of precision. See also

If you need to work with larger numbers as strings in jq you may want to try this library:
