The Wolfram Compiler provides advanced compilation capabilities to process an increasingly wide range of Wolfram Language code into native machine code. A key part of this process is type inferencing. This uses minimal type annotations to determine types for entire functions and groups of functions.

Core Atomic Types

"Boolean" — a Boolean atomic type specifier

"String" — a string type specifier

"InertExpression" — an inert expression type specifier

Integral Types

"Integer8" — an 8-bit machine integer type specifier

"UnsignedInteger8" — an unsigned 8-bit machine integer type specifier

"Integer16" — a 16-bit machine integer type specifier

"UnsignedInteger16" — an unsigned 16-bit machine integer type specifier

"Integer32" — a 32-bit machine integer type specifier

"UnsignedInteger32" — an unsigned 32-bit machine integer type specifier

"Integer64" — a 64-bit machine integer type specifier

"UnsignedInteger64" — an unsigned 64-bit machine integer type specifier

"CSSizeT" — a C ssize_t type specifier

"CFloat" — a C float type specifier

"CDouble" — a C double type specifier

"CArray" — a C array type specifier

"CString" — a C string type specifier

Declaring Compiled Types

TypeDeclaration — a declaration of a product, abstract, macro or alias type

CompiledExpressionDeclaration — a declaration of type representing an expression

Using Compiled Types

Typed — specify a type for a program element such as a function argument

TypeHint — specify a type for a program element inside the body of a function

TypeSpecifier — create a compound type such as a packed array

FunctionCompile — compile Wolfram Language code into optimized machine code
