Accuracy is closely related to precision, also called reproducibility or repeatability, the degree to which further measurements or calculations show the same or similar results.

Unless you define "degree of closeness" you have not defined
anything. Also, by relating precision to measurement, you are using a
quite different concept from that in computing, where "single-
precision", "double-precision" and even "arbitrary-precision" numbers
exist.

Note that in this latter usage, the term "precision" is an indication
of the number of bits used to store a value, and there is an IEEE
standard that is usually implemented for some formats.
