Re:FractionalPart


Juan,

You can try the following routine.

In[43]:=
FractionNew[x_] := Module[{},
      (t1 = Round[x];
        t2 = t1 - x // Chop;
        If[t2 == 0, result = t2, result = FractionalPart[x]];
        result)];

In[47]:=
a = Range[9]^2
x = Exp[.5 Log[a]]
Map[FractionNew[#] &, x]

Out[47]=
{1, 4, 9, 16, 25, 36, 49, 64, 81}

Out[48]=
{1, 2., 3., 4., 5., 6., 7., 8., 9.}

Out[49]=
{0, 0, 0, 0, 0, 0, 0, 0, 0}
