True is returned if the formal series are equal (they should have the same precision) and false is returned if not.
i1 : R=ZZ[x,y] o1 = R o1 : PolynomialRing |
i2 : s = series(x^2+x+y,2) 2 o2 = FormalSeries{x + x + y, 2} o2 : FormalSeries |
i3 : t = series(x+y+1,2) o3 = FormalSeries{x + y + 1, 2} o3 : FormalSeries |
i4 : s == s o4 = true |
i5 : s == t o5 = false |
i6 : r = truncate(t,1) o6 = FormalSeries{x + y + 1, 1} o6 : FormalSeries |
i7 : t == r o7 = false |
