LOGCALC: A Calculator Program Series to Calculate Log Volume, Lumber Recovery, and Log Scale (for a TI-59 Calculator with Printer),
Abstract
Pocket calculators have become as efficient as early large computers. The newest programmable calculators with storage devices such as magnetic cards or tape are essentially small computers. In terms of software, the analogy between computers and calculators can be carried still further. As in the computer field, there is a general lack of special purpose programs that are well documented and easy to use. The main competitors in the programmable calculator market do offer large numbers of documented program for many applications. The applications that this publication addresses, however, are highly specialized and tailored for use by those interested in sawmilling. This calculator program series is designed to be run on magnetic cards on a TI-59 programmable calculator. The following calculations are made by the program series: Log volume by Smalian's Formula; Lumber Recovery Factor; Overlength on logs; and Log scale and percent overrun for the following log rules: Doyle; International 1/4-Inch; Scribner; Scribner Decimal-C; and Bureau Scribner.
