numeric-literal-separators

Group long decimal numeric literals with thousands separators.

SARJ567 Rule source Tests Catalog JSON

Why

Long ungrouped decimal quantities are harder to read and easy to miscount.

Fix

Use three-digit groups such as 10_000_000; retain a named constant when the value has domain meaning.

Examples

Before — flagged The contract is implicit
app/service.py
RATE = 16000
After — preferred The contract is explicit
app/service.py
RATE = 16_000
Autofix output
app/service.py
RATE = 16_000
