5.13.10.
Function I..N generates the NATURAL logarithrn of X, i.e: logarithm
to base e of
X.
Syntax
LN(N)
where
N is a numeric expression.
Examples LN ( 8 )
generates the logarithm to base e of 8, (2.079441601991)
If S=9.12 then:
LN(S)
generates the logari.thm to base e of
9.12.(2,2104698042074)
LN(-91)
generates a 'Magnitude Error' and program execution will
stop.
Remarks X must be greater than zero.
VER.V09F
If X is negative or equal to zero then a 'Magnitude Error'
will occur.
X may be an expression.
