Logarithm and Exponential Functions

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, log
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.
