I have defined a function that takes as arguments small values and also 
returns small values:



However, when plotting the function with
Plot[P1[x], {x, 5.85`*^-17, 7.15`*^-17}]
I get an error message:
Plot::"plld" Endpoints for x in {x, 5.85`*^-17, 7.15`*^-17} must have 
distinct machine-precision numerical values.

I thought Mathematica can handle such small numbers.
Any hint?
