Tomasz Sowa 39db6fc469 fixed: in Big::ToString_CreateNewMantissaAndExponent() changed the formula: ...

new_exp_ = [log base (2^exponent)] + 1
       now the part '+ 1' is only made when the logarithm is positive and with fraction
       if the value is negative we can only skip the fraction, previously
       we lost some last digits from the new mantissa
       
       Consider this binary value (32 bit mantissa):
       (bin)1.0000000000000000000000000000011
       previously ToString() gave 1, now we have: 1.000000001
