RHR-01S: Illegible Numeric Value Representations

Type Severity Location
Code Style RoyaltyHandler.sol:L210

Description:

The linked representations of numeric literals are sub-optimally represented decreasing the legibility of the codebase.

Example:

require(_fee == 100 || _fee == 500 || _fee == 3000 || _fee == 10000, "RoyaltyHandler: Invalid fee");

Recommendation:

To properly illustrate each value's purpose, we advise the following guidelines to be followed. For values meant to depict fractions with a base of 1e18, we advise fractions to be utilized directly (i.e. 1e17 becomes 0.1e18) as they are supported. For values meant to represent a percentage base, we advise each value to utilize the underscore (_) separator to discern the percentage decimal (i.e. 10000 becomes 100_00, 300 becomes 3_00 and so on). Finally, for large numeric values we simply advise the underscore character to be utilized again to represent them (i.e. 1000000 becomes 1_000_000).
