unnecessaryNumericFractions

Reports numeric literals with unnecessary zero fractions or dangling dots.

✅ This rule is included in the ts stylistic presets.

Numeric literals with trailing zero fractions (e.g., 1.0) or dangling dots (e.g., 1.) are unnecessarily verbose and can be confusing. The zero fraction or dangling dot doesn’t add any precision information to the number.

This rule reports numeric literals with unnecessary zero fractions or dangling dots.
