Architecture
Numbers were fixed point variable length (1 to 10 digits). Arithmetic was done in floating point, but all results were converted to fixed point when stored in memory.
Digits are represented in bi-quinary coded decimal. Each digit of memory storage contained 5 tubes. Four of these represented the digits 1, 3, 5, and 7, while for fifth tube represented 9 if activated alone but added 1 to the value if activated together with another tube.
| Digit | 1 | 3 | 5 | 7 | 9 |

Famous quotes containing the word architecture:
“All architecture is great architecture after sunset; perhaps architecture is really a nocturnal art, like the art of fireworks.”
—Gilbert Keith Chesterton (1874–1936)
“Poetry is not only dream and vision; it is the skeleton architecture of our lives. It lays the foundations for a future of change, a bridge across our fears of what has never been before.”
—Audre Lorde (1934–1992)
“Art is a jealous mistress, and if a man have a genius for painting, poetry, music, architecture or philosophy, he makes a bad husband and an ill provider, and should be wise in season and not fetter himself with duties which will embitter his days and spoil him for his proper work.”
—Ralph Waldo Emerson (1803–1882)
