REPETEND, in Arithmetic, signifies that part of an infinite decimal fraction, which is continually repeated ad infinitum. Thus in the numbers 2. 13 13 13 &c. the figures 13 are the repetend and marked thus 13̄. These repetends chiefly arise in the reduction of vulgar fractions to decimals. Thus, \frac{1}{3} = 0.333 \dots &c. = 0.3̄.
