Property getter documentation:

Method to retrieve the numeric collation value. When numeric collation is turned on, this Collator generates a collation key for the numeric value of substrings of digits. This is a way to get '100' to sort AFTER '2'

Java documentation for android.icu.text.RuleBasedCollator.getNumericCollation().

Property setter documentation:

<strong>[icu]</strong> When numeric collation is turned on, this Collator makes substrings of digits sort according to their numeric values.

This is a way to get '100' to sort AFTER '2'. Note that the longest digit substring that can be treated as a single unit is 254 digits (not counting leading zeros). If a digit substring is longer than that, the digits beyond the limit will be treated as a separate digit substring.

A "digit" in this sense is a code point with General_Category=Nd, which does not include circled numbers, roman numerals, etc. Only a contiguous digit substring is considered, that is, non-negative integers without separators. There is no support for plus/minus signs, decimals, exponents, etc.
