Hi, please rebase your PR on fresh master. It has reworked chain interface.

Instead of:

	r.chain.enter("XXX()")
	defer r.leave()

	if r.failed() {
		return r
	}

we should now use:

	opChain := r.chain.enter("Decode()")
	defer opChain.leave()

	if opChain.failed() {
		return r
	}

In other words, chain.enter() now returns a new chain instance, and we should use it for all other operations with chain. This change is part of making this lib thread-safe.

BTW if you don't mind, could you rollback reordering of methods in this PR? No problem with reordering itself, but it makes the diff a mess and it's hard to tell what changed exactly.

[angshumanHalder]

Sure. Would rollback the ordering. Actually When I raised this PR initially I had conflicts which upon resolving messed up the ordering of the functions. I will revert it to initial ordering.

Could you please revert unrelated changes (like formatting) in tests? This is a big pr, and it makes reviewing harder.

[gavv]

Also please remove commented code

[gavv]

Could you also provide a short summary of what is addressed by this pr and what is not?

[angshumanHalder]

Sure. Let me resolve conflicts and revert formatting changes. Give me few days.

[angshumanHalder]

Hey @gavv reverted the formatting changes.

Also short summary -

1. json.Unmarshal() is removed and instead we are using json.Decode()
2. Numbers are converted to big.Float from json.Number() only when there is a precision loss otherwise default float64 is used.
3. numbers are represented in big.Float internally.
