how to get floating point results for taylor expansion?

I've read quite a lot of the manual and experimented with a lot of options.
But I'm unable to get normal floating point numbers or even numbers,
which I can evaluate in visual C++ -- it tells me:

398987622351463743906497032561.0/768.0,e
Error: constant too big


Here is my maxima input:

display2d:false$
debugmode:true$
rest1:(sin(omega*t)-v)^2 + (v - c)^2$
ev(taylor(rest1, [t, v, c], [0, 0, 0], 8), omega=2*3.1415926*1e6);


Kind Regards
