Logarithms and exponential functions
%A
%A
displays two submenus containing the functions
log
,
10^
,
ln
,
and
e^
. Select the submenu, the desired log function,
then enter the value and close the expression with
E <
.
•
log
yields the common logarithm of a number.
•
10^
raises 10 to the power you specify.
•
ln
yields the logarithm of a number ot the base of
e
(
e
2.718281828459).
•
e^
raises
e
to the power you specify.
