Hello,
I've a strange error with the Interpolation function

In[1]:= $Version

Out[1]= 6.0 for Linux x86 (64-bit) (June 19, 2007)

In[2]:= t=Join[{0},10^Range[-8,-2,0.1]];

y=Interpolation[Transpose[{t,Exp[-10000 t]}]]

LogLinearPlot[y[t],{t,10^-6,0.01},PlotRange->All]

Out[3]= InterpolatingFunction[{{0.,0.01}},<>]

During evaluation of In[2]:= InterpolatingFunction::dmval: Input value
{-13.8153} lies outside the range of data in the interpolating function.
Extrapolation will be used. >>

Anyone reproduce or explains it?

Thanks,
Fred.
