Asset exchange in whole numbers

hardcodr

I have use-case where I want to create an offer, but accept the counter-offer only when asset I am offering is exchanged as whole number and not as fraction.
e.g. I am offering 1 GOAT for 100 XLM.
And there are two counter-offers:
1. Account1 selling = 110 XLM for price = 1GOAT for 105 XLM
2. Account2 selling = 55 XLM for price = 1 GOAT for 110 XLM

So although Account2's offer is of higher price, I don't want to sell half a "Goat" to Account2 and then other halt to Account1. I want the offer for Account1 to get execute.

Is this possible?

hardcodr Stellar asset amount is stored as int64, so when you receive 2 XLM, the number is stored as 20000000. So in you case you should set display_decimals=0 in your stellar.toml file (check https://www.stellar.org/developers/guides/concepts/stellar-toml.html).

However, wallets that does not support decimal setting, may show this trade as 0.0000001 GOAT for 100 XLM.

OrbitLens Hi, thanks for reply. As I understand, display_decimals is used to control the displaying of the asset in wallets. You meant to say, stellar-core uses it while executing the offers as well?

He is saying that by default when you issue a new asset, let's say 1 GOAT, that you are actually issuing 10,000,000 GOATs. display_decimals moves the decimal point to make the number easier to read.

In your case, instead of issuing 10,000,000 GOATs you should issue only 1 goat and then set your stellar.toml file to display your asset as 1 GOAT instead of as 0.0000001 GOAT. To issue only 1 GOAT instead of 10,000,000 GOATs, enter 0.0000001 when you issue the asset instead of 1.
