Struct ContinuedFraction 

pub struct ContinuedFraction {
    pub integer_part: i64,
    pub coefficients: Vec<u64>,
}

A continued fraction [a0; a1, a2, …] representing a0 + 1/(a1 + 1/(a2 + …)).

Fields

integer_part: i64

coefficients: Vec<u64>

Implementations

impl ContinuedFraction

pub fn new(integer_part: i64, coefficients: Vec<u64>) -> Self

Create from explicit parts.

pub fn from_rational(num: i64, den: i64) -> Self

Build a continued fraction from a rational number p/q.

pub fn from_f64(x: f64, max_terms: usize) -> Self

Build a continued fraction from a floating point number, computing up to max_terms.

pub fn convergents(&self) -> Vec<(i64, i64)>

Compute convergents (rational approximations) as (numerator, denominator) pairs. Returns all convergents from [a0] to [a0; a1, …, an].

pub fn to_f64(&self) -> f64

Evaluate the continued fraction as an f64.

pub fn len(&self) -> usize

Number of terms (not counting integer part).

pub fn is_empty(&self) -> bool
