The principal data types involved are fixed precision real numbers that are prone to roundoff errors during copmutation. Beyond the data types found in engineering, such as input/output data of numerical software, in computational mathematics, and specifically in scientific computing, including the algorithms, implementations, procedural data, and their metadata descriptions are research data.

There had happened in the teeming and many-towered city of Zeth one of those incidents which are prone to take place in all capitals of all worlds. Nor, simply because Zeth lies on a planet of strange beasts and stranger vegetation, did this incident differ greatly from what might have occurred in London or Paris or any of the great governing towns we know. Through the cleverly concealed dishonesty of an aged but shrewd official, the treasury was exhausted. No shining phrulder, as of old, lay stacked about the strong-room; and over empty coffers the sardonic spider wove webs of mocking design. When, at last, the giphath Yalden entered that obscure vault and discovered the thefts, there were left only some phlegmatic rats which peered sharply at him as at an alien intruder.

There had been no accountings since Kishan the old keeper had died many moon-turns before, and great was Yalden’s dismay to find this emptiness instead of the expected wealth. The indifference of the small creatures in the cracks between the flagstones could not spread itself to him. This was a very grave matter, and would have to be met in a very prompt and serious way. Clearly, there was nothing to do but consult Oorn, and Oorn was a highly portentous being.
