int2 data type

Defines a signed integer in the range [-2, 1].

Data type name

The data type is specified as "int2".

Configuration

None.

Fill value representation

The fill value is specified in the same way as the core integer data types: https://zarr-specs.readthedocs.io/en/latest/v3/core/v3.0.html#fill-value

Codec compatibility

bytes

Encoded as a 1-byte value, 0bIIIIIIXX where the upper IIIIII bits are ignored. The "endian" parameter has no effect. The upper IIIIII bits are arbitrary, but for better compressibility it is recommended to set them to a consistent value when writing.

packbits

Encoded as a 2-bit value.
