How can I avoid jq truncating long decimal

Question

How can I prevent jq from truncating long decimal values?

For example:

echo '18302628978110292481' | jq .

result: 18302628978110292000

It clearly doesn't have the precision you need. Just treat it as a string. — Jeff Mercado, Nov 30 '14 at 17:05

Those links do not have any answers. I could not find any solution using the jq, so I decided to do a "find using regex and replace" in the input json file, and enclosed all numbers with quotes to make them strings. — MiroJanosik, Jan 31 '23 at 21:50

Javascript does not support such big numbers and so does jq. The integer size is 2^53. Check this

To make it work, you'll need to treat them as strings:

echo '"18302628978110292481"' | jq .
# Prints "18302628978110292481"
