In general, what floating point precision standard does Binance use when calculating the prices, volumes, etc

Query exchangeInfo endpoint → PRICE_FILTER → tickSize. The decimal places of the value in tickSize will decide the allowed precision for the symbol.

Thank you for reply. And for floating point calculation, which standard are you using?

Is it IEEE 754 ?

How is the precision handled? Are numbers rounded anyhow or the math result is simply truncated to match the given precision?
