(1) It supports trigonometric functions, logarithm and antilogarithm .(2) If the logarithm is taken as the forward function, the function taking the base to a given power is then called the antilogarithm .(3) Adjusted geometric means (often approximating median values) were computed by back transformation (taking the antilogarithm ).(4) Values at the tick marks were converted to their antilogarithms .(5) All equations are fitted by the reduced major axis algorithm to the logarithms of the original data; the data were then transformed to their antilogarithms to return to the original units.
