Singular

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[/code]

assuming that somewhere a ring is declared (by ot hers), lets say

[code]ring R = (real,55,57),x,dp;[/code]

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);[/code]

?
