浮点数
The Nord-10 had 160 registers, of which 128 were available to programs, eight on each of the 16 program levels. Six of those registers were general registers, one was the program counter, and the other contained status information. Floating point operations were standard. The instructions could operate on five different formats, a bit, an 8-bit byte, 16-bit words, 32-bit double words, and 48-bit floating point words.
