You can declare inline numbers using `Cast(value)`. It is useful for `Int8`/`Uint8` and `Int16`/`Uint16` for example: ```swift // Fake function to use: public static func UseNumber(a: Int8, ua: Uint8, b: Int16, ub: Uint16) -> Void; // Use explicit cast UseNumber(Cast(127), Cast(255u), Cast(32767), Cast(65535u)); ``` ## Floating-Point Types

`String` values are stored internally as a null-terminated character array, unfortunately the bytecode doesn't support accessing the individual characters as an array. `CName` values are stored in-engine as a [64-bit hash key](https://en.wikipedia.org/wiki/Fowler%E2%80%93Noll%E2%80%93Vo_hash_function#FNV-1a_hash) to a interned string pool. Class, function and field names are stored in the CName pool, so any methods that need a dynamic reference a scripted component will use a `CName` value. `ResRef` values are similar to `CName` values, except they specifically refer to archive resource files and presumably use a separate optimized string pool. Unlike `CName`, `ResRef` doesn't have any defined operators. `TweakDBID` is used as the primary key for all `*_Record` types stored in TweakDB, the engine's internal database. ## Other Types

VariantA dynamic type that can store any other type
## Operators The RED4 scripting runtime implements most operators as native functions. Only the equals `==` and not equals `!=` operators are implemented in bytecode. The **redscript** compiler provides a number of operator symbols as shorthand. This table lists the available operators (in precedence block order) and what types support them.

### Notes 1. The Logical Not `!` operator for `TweakDBID` is overridden to return `!TDBID.IsValid(a)` 2. Strings can be multiplied by an `Int32` to repeat the string: ```swift public static func OperatorMultiply(a: String, count: Int32) -> String ``` 3. `String` addition is [concatenation](https://en.wikipedia.org/wiki/Concatenation). There are native functions to allow most types can be concatenated with `String` 4. `CName` and `TweakDBID` addition is [concatenation](https://en.wikipedia.org/wiki/Concatenation) (and presumably involves some kind of internal lookup to a known value) 5. The **redscript** compiler doesn't currently support the `==` and `!=` symbols for the `CName` type, use the `Equals(a,b)` and `NotEquals(a,b)` intrinsic functions for now. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
