All Bundles

Bundle Core runtime library providing primitive types (Bool, Byte, Char, Int, Float, String), base collections, and system utilities. Every Objeck program links against this bundle automatically via lang.obl.

Int

Integer class represents an operating system long value

Inherits: Number

n := Int->Random(100);         # random 0–99
abs := Int->Abs(-42);          # 42
mx  := Int->Max(10, 20);       # 20
Int->Sort(v);                  # sort int array in-place
