Spot market

1. UI human readable to chain format: Using INJ/USDT market which has 18 base decimals and 6 quote decimals as an example, here’s how we convert the value to the chain format:

import { toChainFormat } from "@injectivelabs/utils";

const value = toChainFormat(value, quoteDecimals - baseDecimals).toFixed();

2. Chain format to UI human readable format: Using INJ/USDT market which has 18 base decimals and 6 quote decimals as an example, here’s how we convert the value to the UI human readable format:

import { toHumanReadable } from "@injectivelabs/utils";

const value = toHumanReadable(value, quoteDecimals - baseDecimals).toFixed();

Derivative market

1. UI human readable to chain format: Using INJ/USDT perp market which has 6 quote decimals as an example, here’s how we convert the value to the chain format:

import { toChainFormat } from "@injectivelabs/utils";

const value = toChainFormat(value, -quoteDecimals).toFixed();

2. Chain format to UI human readable format: Using INJ/USDT perp market which has 6 quote decimals as an example, here’s how we convert the value to the UI human readable format:

import { toHumanReadable } from "@injectivelabs/utils";

const value = toHumanReadable(value, quoteDecimals).toFixed();
