D       C   (multi-tap keys)

D pastes the natural logarithm, ln, of a number to the base e. The argument of the function is ln(value).

e ≈ 2.718281828459 for calculations.

e ≈ 2.718281828 for display in Float mode.

D D pastes the common logarithm, log10, of a number. The argument of the function is log(value).

D D D pastes the logBASE function as a MathPrint™ template. When needed, the arguments in classic entry are logBASE(value,base).

C pastes e to the power function.

C C pastes 10 to the power function.
