Re: LN() & Log() LOG Base

Use the change of base formula

log(base a) of x = (ln x)/(ln a)

for log(base 2) of  8 enter:    ln(8)/ln(2)
the result is 3

Define the following function

Define log2(x)=ln(x)/ln(2)

>From now on, simily type log2( a number ) on the command
line and you will get the log(base 2) of the number.
You may have to use the approximate key to avoid the
exact result.  [diamond][enter]
