Hi all:

I have a question here about expanding equations,

y=(681955671395281*x^4)/562949953421312 - (997579897589123*x^3)/1125899906842624 - (9828045527386765*x^2)/4503599627370496 + (4528831679417155*x)/18014398509481984 + 8732253082293499/18014398509481984

I would like the coefficients of y are in decimal, say, 12 digits, how do i do it?

Thanks in advance.
