Item Description

Data encoding of a single element of array data. The type 'unsigned 1-bit integer' is used for packed Boolean arrays for masks. Each element of the array corresponds to a single bit packed in unsigned 8-bit data. In several cases, the IEEE format is referenced. See IEEE Standard 754-1985 (IEEE, 1985). Reference: IEEE (1985). IEEE Standard for Binary Floating-Point Arithmetic. ANSI/IEEE Std 754-1985. New York: Institute of Electrical and Electronics Engineers.
