Struct EvalConfig 

pub struct EvalConfig {
    pub max_pow_exponent: usize,
    pub max_result_digits: usize,
    pub max_evalf_precision: u32,
}

Controls the bounds on automatic evaluation in constructors.

These guards prevent runaway computation from pathological inputs like 7^(10^100) which would allocate astronomical amounts of memory.

Fields

max_pow_exponent: usize

Maximum integer exponent for automatic evaluation of pow().

If the exponent exceeds this, pow() returns an unevaluated Pow node instead of computing the result.

Default: 1000.

max_result_digits: usize

Maximum digits in a numeric result before we refuse to auto-evaluate.

Default: 5000.

max_evalf_precision: u32

Maximum working precision (in bits) for evalf() before giving up.

Default: 10,000.
