tertiary operator error casting Float to Object

[Alex Buckley]

On JDK 17.0.6, for example, I get the expected result (temp = 60.0) 
which is the correct result.

Which JDK version are you using?

(For the record: per JLS 15.25.2 and 5.6, the type of the numeric 
conditional expression `isInt ? ... : ...` is float, which is assignment 
compatible with Object.)
