Struct ArbitraryFloat 

pub struct ArbitraryFloat { /* private fields */ }

Arbitrary precision floating-point number backed by oxinum_float::DBig (Pure Rust).

DBig is a base-10 decimal big-float. The ArbitraryPrecisionContext stores precision in bits (for API stability), but all oxinum calls receive the equivalent decimal-digit count.

Implementations

impl ArbitraryFloat

pub fn new() -> Self

Create a new zero-valued arbitrary precision float with the default precision.

pub fn withprecision(prec: u32) -> CoreResult<Self>

Create with a specific bit precision.

pub fn with_context(context: ArbitraryPrecisionContext) -> Self

Create with a specific precision context.

pub fn from_f64(v: f64) -> Self

Create from f64 with the default precision.

pub fn from_f64_withprecision(v: f64, prec: u32) -> CoreResult<Self>

Create from f64 with a specific bit precision.

pub fn from_strprec(s: &str, prec: u32) -> CoreResult<Self>
