Hello.
I am new in Mathematica(also in english), and I have this question:
I would like to know the behavior of the function FractionalPart.
See here:
In[1]:= a=Range[9]^2
Out[1]= {1,4,9,16,25,36,49,64,81}
In[2]:= x=Exp[.5 Log[a]]
Out[2]= {1,2.,3.,4.,5.,6.,7.,8.,9.}
In[3]:= FractionalPart[x]
Out[3]= {0,0.,4.444089x10^-16,0.,0.,1.,0.,0.,1.,1.77639x10^-15}
But it shoud be 0., all of them,no?
Thanks. Juan
