Type:

Bug?

Severity:

Medium

Description:

Hi,
Looks like ipfs CLI (ipfs dag put ) serializes integers in DAGs as double-precision floats, is this a bug or intentional decision?

example:
echo '{"var":1}' | ipfs dag put
zdpuAxQm7QaVc9ufEyKcqNX35WLw7LwdtYkhD4ksvuvaeeaBW

test:
ipfs block get zdpuAxQm7QaVc9ufEyKcqNX35WLw7LwdtYkhD4ksvuvaeeaBW | xxd
00000000: a163 7661 72fb 3ff0 0000 0000 0000 .cvar.?.......

Thanks
Leo

See: ipld/interface-ipld-format#9. There are a lot of decisions we need to make concerning primitive types in IPLD.

@Stebalien thanks for the reference, I probably missed the earlier thread. Looking at ipld/interface-ipld-format#9 , i tend to agree with @kevina 's proposal, but I might not be aware of all the moving parts
