Enum Budget 

pub enum Budget {
    Fast,
    Balanced,
    Precise,
}

Working-precision preset requested by the caller.

A budget selects only the working precision. It deliberately does not change method defaults, tolerances, or convergence criteria: different algorithms have different conditioning, and a tighter requested tolerance does not by itself produce a more accurate answer. Iterative methods report their own requested tolerance, error estimate, residual, and convergence status as separate fields, and decimal calculations that round still report rounded.

Variants

Fast

15 significant digits.

Balanced

34 significant digits (default).

Precise

100 significant digits.
