Returns the natural logarithm of a number.
Synopsis
The
LN function returns the natural logarithm of
number. The
number value must be a nonzero positive number; all other values generate an <ILLEGAL VALUE> error.
The
LN function complements the action of the
EXP function, which is sometimes referred to as the antilogarithm.
The following example uses the
LN function to calculate the natural logarithm of each of the integers 1 through 10:
FOR x=1 TO 10
PRINT "Natural log of ",x," = ",LN(x)
