1.12 + ECMA Section: 15.8.2.10 Math.log(x)
1.13 + Description: return an approximiation to the natural logarithm of
1.14 + the argument.
1.15 + special cases:
1.16 + - if arg is NaN result is NaN
1.17 + - if arg is <0 result is NaN
1.18 + - if arg is 0 or -0 result is -Infinity
1.19 + - if arg is 1 result is 0
1.20 + - if arg is Infinity result is Infinity
