3-59
3.2.57 LN_ - NATURAL LOGARITHM
LN_
function blocks, in firmware 1.30 and higher, will output the
natural logarithm of input X. When the input is <= 0.0, the input will
be treated as the smallest number greater than 0.0 (i.e. 1.17....e-38) and
the LN will be computed accordingly.

3.2.58 LOG_ - LOGARITHM BASE 10
LOG__
function blocks, in firmware 1.30 and higher, will output
the logarithm to the base 10 of input X. When the input is <= 0.0,
the input will be treated as the smallest number greater than 0.0
(i.e. 1.17....e-38) and the LOG will be computed accordingly.
