+  round(x, n)         - Rounds x to n decimal places (default 0)
+  floor(x)            - Returns the floor of x
+  ceil(x)             - Returns the ceiling of x
+
+STRING FUNCTIONS:
+  upper(s)            - Converts string to uppercase
+  lower(s)            - Converts string to lowercase
+  format(s, ...)      - Formats string using Lua string.format
+  trim(s)             - Removes leading/trailing whitespace
+  strsplit(inputstr, sep) - Splits string by separator (default: whitespace)
+  num(str)            - Converts string to number (returns 0 if invalid)
+  str(num)            - Converts number to string
+  is_number(str)      - Returns true if string is numeric
+
+TABLE FUNCTIONS:
+  DumpTable(table, depth) - Prints table structure recursively
+  isArray(t)          - Returns true if table is a sequential array
+
+HTTP FUNCTIONS:
+  fetch(url, options) - Makes HTTP request, returns response table
+    options: {method="GET", headers={}, body=""}
