How to convert a big decimal to hex in bash?-CodePudding

I need to convert a very big number in its hex form (no spaces, no anything e.g. 8ac7230489e80001). Using printf gives an out of range error.

printf '%x\n' "24267339429148234667523"

-bash: printf: warning: 24267339429148234667523: Numerical result out of range
ffffffffffffffff

I tried other methods (python), but it seems they only give a string output. I still need it to be a number. Is it possible to handle numbers larger like this?

Decimal to hex:

echo 'obase=16; 24267339429148234667523' | bc

and the other way around:

echo 'ibase=16; 52388FCBCEF833CD603' | bc

You can use the bc utility:

bc <<< 'obase=16;24267339429148234667523'
