Handle Big Numbers

Sentio SDK uses javascript's native bigint for big integer calculations. However, if you want to do operations like division, you need to convert it to BigDecimal , otherwise, you may lose precision during the operation. We do provide utils for bigint and other type like BN to convert to BigDecimal.

const latestAnswer: bigint = 10n

// Use asBigDecimal to convert bigint to BigDecimal
const eth_usdc_price: BigDecimal = latestAnswer.asBigDecimal().div(BigDecimal(10).pow(18))

// Use scaleDown to further simplify code in some cases.
const eth_usdc_price2: BigDecimal = latestAnswer.scaleDown(18)
