Defines the fundamental data types supported by tensors and provides utilities for:

Supported Data Types

The type enum defines all supported numeric types:

enum type {
    none,       // Invalid type 
    boolean     // 1-bit-packed boolean (true, false).
    int8,       // 8-bit integer
    int16,      // 16-bit integer
    int32,      // 32-bit integer
    int64,      // 64-bit integer
    float16,    // 16-bit float
    float32,    // 32-bit float
    float64,    // 64-bit float (double)
    complex64,  // 64-bit complex (two float32)
    complex128, // 128-bit complex (two float64)
    TYPES       // Count of types
};

Key Functions

• dsizeof(type): Returns byte size of a type
• dnameof(type): Returns string name of a type
• dcodeof(type): Returns numeric code for serialization
• dtypeof(code): Converts code back to type enum
• operator<<: Stream output support

Example

std::cout << dnameof(float32); // "float32" std::cout << dsizeof(complex128); // 16
