is JQ Transform modifying numbers? How can I get past it?

Question

Why this (\"Filter\" in jqplay.org): {\"key\":633447818234478180}

returns this (\"Result\" in jqplay.org): {\"key\": 633447818234478200}

Original JSON doesn\'t m

Answer 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:
