[18] [19] Thus, such a table served a similar purpose to tables of logarithms, which also allow multiplication to be calculated using addition and table ...

    The first three rows in the table below reproduce the headings and first two data rows of the left-side 19 degree page of Napier's table, see photograph. They are followed by values computed using modern algorithms for the same angles. [6] These are truncated to 8-digit accuracy, one more than the nominal 7-digit accuracy of Napier's table.

    [13]: p. 8, archive p. 32) Lattice multiplication, used by Fibonacci, was made more convenient by his introduction of Napier's bones, a multiplication tool using a set of numbered rods. Napier may have worked largely in isolation, but he had contact with Tycho Brahe who corresponded with his friend John Craig.
