Enum Constant Details

QUInt8

public static final ScalarType QUInt8

8-bit quantized unsigned tensor type which represents a compressed floating point tensor.

QInt8

public static final ScalarType QInt8

8-bit quantized signed tensor type which represents a compressed floating point tensor.

Int8

public static final ScalarType Int8

8-bit integer.

Int16

public static final ScalarType Int16

16-bit integer.

Int32

public static final ScalarType Int32

32-bit integer.

Int64

public static final ScalarType Int64

64-bit integer.

BFloat16

public static final ScalarType BFloat16

The bfloat16 (brain floating point) floating-point format occupies 16 bits. This format is a shortened version of the 32-bit IEEE 754 single-precision floating-point format. It preserves the approximate dynamic range of 32-bit floating-point numbers by retaining 8 exponent bits, but supports only an 8-bit precision rather than the 24-bit significand of the single precision.

Float16

public static final ScalarType Float16

Half-precision floating-point number. It contains 5 exponent bits and 11 11-bit precision (10 explicitly stored).

Float32

public static final ScalarType Float32

Single-precision floating-point number.

Float64

public static final ScalarType Float64

Double-precision floating-point number.

Method Details

values

public static ScalarType[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static ScalarType valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null
