cangjie-basic-data-type

Cangjie basic data types include integers (Int8–Int64, UInt8–UInt64), floats (Float16–Float64), Bool, Rune, String, Unit, Nothing, Tuple, Array, VArray, and Range. These foundational types enable reliable program construction with defined type rules and literals.

To convert between Rune and UInt32 in Cangjie, apply the core type conversion rules and operators. This Skill provides practical examples showing how to safely switch between Rune and integer representations for character processing.

VArray represents a fixed-size array in Cangjie, whereas standard Array provides dynamic sizing. This distinction dictates how you manage memory and create collections, with VArray requiring predefined capacity constraints.

Iterate over a Cangjie String by bytes or by runes using specific core operators and patterns. This Skill demonstrates common iteration techniques to handle text data accurately according to type rules.

Use the Unit type in Cangjie when a function returns no meaningful value, and Nothing for unreachable code or non-returning scopes. These types enforce control flow reliability and strict type checking during compilation.
