If wrapped primitive values (e.g. Integers and Floats) are used in a ternary operator (e.g. a?b:c), both values will be unboxed and coerced to a common type, potentially leading to unexpected results. To avoid this, add an explicit cast to a compatible type.

Noncompliant Code Example

Integer i = 123456789;
Float f = 1.0f;
Number n = condition ? i : f;  // Noncompliant; i is coerced to float. n = 1.23456792E8


Compliant Solution

Integer i = 123456789;
Float f = 1.0f;
Number n = condition ? (Number) i : f;  // n = 123456789
