I am using python ccxt to place a sell order on binance.

order = exchange.create_order(symbol, 'market', 'sell', amount)

I have fetched the required precision, and got 5.

markets = exchange.load_markets()
amount_precision = market['precision']['amount']

So, I set the precision of amount, which was originally 0.0002535009794671468384415698887 to 5, and got 0.00025.

But when I create an order with this amount value, I get the error:

binance amount of BTC/USDT:USDT must be greater than minimum amount precision of 3

Although I have set the precision to 5, which was the required value.

What does precision really mean in the binance api? Is it the number of significant digits? I need some clarification.
