Field notes
The keypad supports 1/8-inch, 1/16-inch and 1/32-inch precision, and accepts desktop keyboard input for feet, inches, fractions and arithmetic. Its instructions describe storing rise, run, pitch or diagonal values, then cycling through stair measurements or successive jack and rake lengths. The page also gives the hip/valley formula and names geometry and framing-square tables as sources. Results are explicitly estimates, with a warning to verify them with a licensed engineer and local building department.
