9 ECMA Section: 15.8.2.10 Math.log(x)
10 Description: return an approximiation to the natural logarithm of
11 the argument.
12 special cases:
13 - if arg is NaN result is NaN
14 - if arg is <0 result is NaN
15 - if arg is 0 or -0 result is -Infinity
16 - if arg is 1 result is 0
17 - if arg is Infinity result is Infinity
