Marchant Tables of Factors for Square Roots

<< >>
Description
These two paper leaflets provide numerical values needed for finding square roots to eight significant digits (Table No. 80) and to six significant digits (Table No. 81). Table 80 was copyrighted in 1951, Table 81 in 1952. These copies of the tables were issued after Marchant became a division of Smith-Corona Marchant Inc. in 1958.
Table 80 allows one to compute square roots on a calculating machine to eight significant digits using a combination of additions and two divisions. Table 81 allows one to find less precise values of the same function using additions and only one division.
Compare to MA*313984.03.
