"Don't use a static_cast for arithmetic conversions. Use brace initialization, gsl::narrow_cast, or gsl::narrow."

Brace initializers are better for the cases where constants are used, and a compiler error is desired. There are also utilities from the Guidelines Support Library that help to describe intentions clearly:
