Hello MathGroup,
My last confession was...
er...
NSolve seems able to carry through significance arithmetic. FindRoot
and NDSolve seem inable to do so.
I would like to be able to solve the following equation for acCap[0]
assuming cNapRatio->0
(sorry about the FullForm, but I had to rid the post of the one way
Notations I made), does anyone know a way to get Mathematica to do
this?

Equal[Times[Power[Log[10],-1],Log[acCap[cNapRatio]]],
  Plus[Times[0.6107999999999999999`0.9956786262173576,cNapRatio],
    Times[-2.0360000000000000001`2.9999999999999996,
      Plus[Times[-0.0061540230743798795`0.9978339382434933,
          Power[acCap[cNapRatio],-2],
          Power[Power[acCap[cNapRatio],2],Rational[1,2]]],
        Times[Power[2,Rational[-1,2]],
          Power[Plus[Times[2,cNapRatio],
              Times[0.0410268204958658633`3.3010299956639817,
                Power[acCap[cNapRatio],-2],
                Power[Power[acCap[cNapRatio],2],Rational[1,2]]]],
            Rational[1,2]],
          Power[Plus[1,
              Times[Power[2,Rational[-1,2]],
                Power[Plus[Times[2,cNapRatio],
                    Times[0.0410268204958658633`3.3010299956639817,
                      Power[acCap[cNapRatio],-2],
                      Power[Power[acCap[cNapRatio],2],Rational[1,2]]]],
                  Rational[1,2]]]],-1]]]]]]
