On some values, like 1.99 (3.99 and so on) log() function
give too worse results.  For example:
    log(1.999) --> 0.693
    True value   = 0.688
The reason is that the evaluation method is not suitable for
its rigth margin.
   To correct this I have add extra polynom for such values.
Size is slightly increase, approx. 20 words.

Possible, it is needed to review all libm's functions.
