PyWAVES Order Format - Normalization

With regards to the normalization of quantities used in DEX orders, https://docs.waves.tech/en/blockchain/order#order-s-amount-and-price indicates:

“in version 1, 2, 3 orders: amount × price × 10^-8
version 4 orders: amount × price × 10^(priceAssetDecimals - amountAssetDecimals - 8)”

My question is, which format should I use with PyWaves?
