Submission Details
Severity:
Use scientific notation (e.g. `1e18`) rather than exponentiation (e.g. `10**18`)
Summary
Use scientific notation (e.g. 1e18) rather than exponentiation (e.g. 10**18)
Vulnerability Details
While the compiler knows to optimize away the exponentiation,
it's still better coding practice to use idioms that do not
require compiler optimization, if they exist.
