Module precision 

Hyperliquid’s precision rules for order sizes and prices, and the check an order passes before it is sent.

From Hyperliquid’s tick and lot size rules:

• A size has at most the asset’s szDecimals decimal places.
• A price has at most 5 significant figures, and at most MAX_DECIMALS - szDecimals decimal places, where MAX_DECIMALS is 6 for perpetuals and 8 for spot. An integer price is always valid, whatever its number of significant figures.

A spot pair’s szDecimals is its base token’s.
