assuming that somewhere a ring is declared (by ot hers), lets say Code: ring R = (real,55,57),x,dp; is there a Singular function to get the number of digits like Code: int R_digits ; int R_restdigits; R_digits = digits(R); R_restdigits = restdigits(R); ? |

Apologies if I misunderstood your question, If you want to recover details of declared ring, use ringlist command. For example, Code: ring r = (real,55,57),x,dp;
ringlist(r); //Displays information regarding current ring as array of arrays. Now, int R_digits =ringlist(r)[1][2][1]; //55 int R_restdigits = ringlist(r)[1][2][2]; //57 |
