Type Conversion

Conversion is possible both implicitly and explicitly in Solidity. If no data loss or contradiction in rules is anticipated, the Solidity compiler allows for implicit conversions. For example, uint8 can be implicitly converted to uint16 because both are unsigned integers, and the latter has a wider range. On the other hand, int8 can only be explicitly converted to uint256, even though int8 can hold negative values, which aren’t allowed in uint256. In such cases, explicit conversion is necessary to ensure that we’re aware of the data type changes in our code. This feature provides us with the flexibility to work seamlessly across different data types while maintaining the integrity of our smart contracts.
