Return a Z3 rational number that approximates the algebraic number `self`. The result `r` is such that |r - self| <= 1/10^precision >>> x = simplify(Sqrt(2)) >>> x.approx(20) 6838717160008073720548335/4835703278458516698824704 >>> x.approx(5) 2965821/2097152

| def as_decimal | ( | self, | |
| prec | |||
| ) |
Return a string representation of the algebraic number `self` in decimal notation using `prec` decimal places. >>> x = simplify(Sqrt(2)) >>> x.as_decimal(10) '1.4142135623?' >>> x.as_decimal(20) '1.41421356237309504880?'
