updating oE log
Logarithms and Powers
log
<builtin> function log(object value)
returns the natural logarithm of a positive number.
Parameters:
 value : an object, any atom of which log acts upon.
Returns:
An object, the same shape as value. For an atom, the returned atom is its logarithm of base E.
Errors:
If any atom in value is not greater than zero, an error occurs as its logarithm is not defined.
Comments:
This function may be applied to an atom or to all elements of a sequence.
To compute the inverse, you can use power(E, x) where E is 2.7182818284590452, or equivalently exp(x). Beware that the logarithm grows very slowly with x, so that exp grows very fast.
Example 1:
a = log(100)  a is 4.60517
