The contribution

Contributor	URL	Project	Score
@victorier	Error on "Estimated Account Value" in wallet	steemit	0

@victorier, a first-time contributor to the category, she discovered an estimation error in the steem wallet, in her words "either she's been made a millionaire or there was an error at play ", she hoped the former was the case :) . Unfortunately, a similar report had been submitted to the steemit/condenser issues page. The contribution was reviewed by @tobias-g who advised the new millionaire on how best to contribute to utopian.io and the bug-hunting category in particular.

First of all, it's great to see that you're trying to get involved with helping the Steemit team by reporting issues about the Condenser. I can even see that you reported this on Github (https://github.com/steemit/condenser/issues/3102) which is great. With that said this particular issue is not something that can be rewarded by Utopian, this is because of this particular issue has already been reported on GitHub prior to your report. This can be found here:

https://github.com/steemit/condenser/issues/3101

Though the contribution was tagged a duplicate, a fix was duly appropriated by the steemit team. The problem is explicitly explained below as it was also experienced in the steem-js library.

This line fails to divide by the quote part of the feed price ratio and therefore computes an incorrect price when the quote is not 1.000.

https://github.com/steemit/steem-js/blob/master/src/formatter.js#L103

This is the case currently as the consensus logic is adjusting the feed price to maintain the 10% SBD to STEEM market cap limit, resulting in a complex ratio: "median_sbd_price": { "base": "122615385.381 SBD", "quote": "283814541.914 STEEM" }. It could also occur if witnesses started reporting the price feed using a quote other than 1.000. For example, this could happen at very low STEEM prices, in order to enable more than three fractional digits.

This is now causing incorrect output in many UIs

Cause

        if (feed_price && feed_price.has('base') && feed_price.has('quote')) {
            const { base, quote } = feed_price.toJS();
            if (/ SBD$/.test(base) && / STEEM$/.test(quote))
                price_per_steem = parseFloat(base.split(' ')[0]);
                
        }

The error in estimation is as a result of this line price_per_steem = parseFloat(base.split(' ')[0]);

Fix

        if (feed_price && feed_price.has('base') && feed_price.has('quote')) {
            const { base, quote } = feed_price.toJS();
            if (/ SBD$/.test(base) && / STEEM$/.test(quote))
                price_per_steem =
                    parseFloat(base.split(' ')[0]) /
                    parseFloat(quote.split(' ')[0]);
        }
