Numbers within strings are compared using numeric value, that is,
- iOS 2.0+
- macOS 10.3+
- UIKit for Mac 13.0+Beta
- tvOS 9.0+
- watchOS 2.0+
Numeric comparison only applies to the numerals in the string, not other characters that would have meaning in a numeric representation such as a negative sign, a comma, or a decimal point.
This option only applies to compare methods, not find.
