Singular Manual: bounds

| #### D.15.30.1 bounds Procedure from library `rootisolation.lib` (see rootisolation_lib). Usage: `bounds(a)`; `a number`; `bounds(a, b)`; `a, b number`; Return: interval: if `size(#)==0` it returns the interval `[a, a]`, else the interval `[a,#[1]]` Example:
    LIB "rootisolation.lib";
    ring R = 0,x,dp;
    interval I = bounds(1);
    I;
    ==> [1, 1]
    interval J = bounds(2/3,3);
    J;
    ==> [2/3, 3]
