Inspectopedia 2025.2 Help

Confusing floating-point literal

Reports any floating point numbers that don't have a decimal point, numbers before the decimal point, or numbers after the decimal point.

Such literals may be confusing, and violate several coding standards.

Example:

double d = .03;

After the quick-fix is applied:

double d = 0.03;
