'compare()' method can be used to compare numbers
Reports expressions that can be replaced by a call to the Integer.compare() method or a similar method from the Long, Short, Byte, Double or Float classes, instead of more verbose or less efficient constructs.
If x and y are boxed integers, then x.compareTo(y) is suggested, if they are primitives Integer.compare(x, y) is suggested.

Locating this inspection
- By ID
Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.
UseCompareMethod- Via Settings dialog
Path to the inspection settings via IntelliJ Platform IDE Settings dialog, when you need to adjust inspection settings directly from your IDE.
Note that Double.compare and Float.compare slightly change the code semantics. In particular, they make -0.0 and 0.0 distinguishable (Double.compare(-0.0, 0.0) yields -1). Also, they consistently process NaN value. In most of the cases, this semantics change actually improves the code. Use the checkbox to disable this inspection for floating point numbers if semantics change is unacceptable in your case.
