TNG-01S: Illegible Numeric Value Representation

Description:

The linked representation of a numeric literal is sub-optimally represented decreasing the legibility of the codebase.

Example:

contracts/TNGBLV3Oracle.sol
14uint24 public constant poolFeeDefault = 3000;

Recommendation:

To properly illustrate the 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).

Alleviation (1f394a00cc2ed1dc2020a9c07f982cff9029077d):

After discussing with the Tangible team, we deduced that the value referenced by this exhibit refers to a 0.3% percentage meaning that no underscore delimiter should be introduced.

As such, we consider this exhibit to be invalidated.
