Class: RuboCop::Cop::Style::NumericLiteralPrefix
- Includes:
- IntegerNode
- Defined in:
- lib/rubocop/cop/style/numeric_literal_prefix.rb
Overview
This cop checks for octal, hex, binary and decimal literals using uppercase prefixes and corrects them to lowercase prefix or no prefix (in case of decimals). eg. for octal use ‘0o` instead of `0` or `0O`.
Can be configured to use ‘0` only for octal literals using `EnforcedOctalStyle` => `zero_only`
