  • addAllIfNotNull - Returns a new set with all non-null elements added
  • firstWhereOrNull - Returns the first element matching a predicate or null
  • slice - Returns a new set with elements at specified indices
  • containsAll - Checks if set contains all elements from another iterable
  • containsAny - Checks if set contains any elements from another iterable
  • groupBy - Groups elements into a map of sets by a key function

  • chunked - Splits the set into chunks of given size
  • sorted - Returns a new set with elements sorted by a compare function
  • sortedBy - Returns a new set sorted by a key function
  • sortedByDescending - Returns a new set sorted in descending order by a key function

• Enhanced NumExtension with comprehensive utility methods:

  • Number Formatting

    • formatted - Adds thousand separators (e.g., 1,234,567)
    • toCurrency - Formats number as currency with locale support
    • percentage - Formats number as percentage

  • Mathematical Utilities

    • isEven - Check if number is even
    • isOdd - Check if number is odd
    • isPositive - Check if number is positive
    • isNegative - Check if number is negative
    • isZero - Check if number is zero
    • isInteger - Check if number is an integer
    • clamp - Restrict number to a range
    • isBetween - Check if number is in range
    • isPrime - Check if number is prime
    • factorial - Calculate factorial

  • Range Utilities

    • until - Create range (exclusive)
    • to - Create range (inclusive)

  • Conversion Utilities

    • toRoman - Convert to Roman numerals
    • toRadians - Convert degrees to radians
    • toDegrees - Convert radians to degrees
    • toOrdinal - Convert to ordinal string (1st, 2nd, 3rd, etc.)

• Added new List Extensions:

  • elementAtOrNull - Returns the element at index or null if out of bounds
  • singleWhereOrNull - Returns single matching element or null if none/multiple found
  • reduceOrNull - Returns reduced value or null if list is empty
  • indexWhereOrNull - Returns first matching index or null if not found
  • lastIndexWhereOrNull - Returns last matching index or null if not found
  • indexOfOrNull - Returns first index of element or null if not found
  • lastIndexOfOrNull - Returns last index of element or null if not found
  • removeLastOrNull - Removes and returns last element or null if empty
  • removeAtOrNull - Removes and returns element at index or null if out of bounds
  • removeOrNull - Removes first occurrence and returns success boolean
