LOG: Logarithm, Optional 2nd Argument is Base
LOG(x) computes the natural logarithm of x. LOG(x,b) computes the base b logarithm of x. The inverses are EXP(x) and b**x resp.

result = LOG ( x )
computes the
natural_logarithm
(base e) of x, e.g.:
y = LOG( 10 )
! y is set to 2.302585093
result = LOG ( x , b)
computes the
base_b_logarithm
of x, e.g.:
y = LOG( 100, 10 )
! y is set to 2
the inverse function to LOG is
EXP
, e.g.
x =
EXP
( 2.302585093 )
! x is set to 10
the inverse function to LOG(x, base) is base**x (or base^x), e.g.
x = 10**2
! x is set to 100
