Style/NumericLiterals

Safe autocorrect: Yes
✅ The autocorrect a cop does is safe (equivalent) by design.

Description

Overview

Checks for big numeric literals without _ between groups
of digits in them.

Additional allowed patterns can be added by adding regexps to
the AllowedPatterns configuration. All regexps are treated
as anchored even if the patterns do not contain anchors (so
\d{4}_\d{4} will allow 1234_5678 but not 1234_5678_9012).

NOTE: Even if AllowedPatterns are given, autocorrection will
only correct to the standard pattern of an _ every 3 digits.

Examples

# bad
1000000
1_00_000
1_0000

# good
1_000_000
1000

Strict: false (default)

# good
10_000_00 # typical representation of $10,000 in cents

Strict: true

# bad
10_000_00 # typical representation of $10,000 in cents

AllowedNumbers: [3000]

# good
3000 # You can specify allowed numbers. (e.g. port number)
