Struct CachedFBig 

pub struct CachedFBig { /* private fields */ }

A float stored at extra working precision so later requests at lower (or equal) precision reuse the cache instead of recomputing.

Implementations

impl CachedFBig

pub fn new(inner: ExactNum) -> CachedFBig

Wrap an already-computed value, retaining its current mantissa width.

pub fn cached_bit_len(&self) -> Option<usize>

Cached mantissa width in bits (None for Inf / NaN).

pub fn inner(&self) -> &ExactNum

The stored value.

pub fn round(&self, p: usize, rm: RoundingMode) -> ExactNum

Round the cached value to p bits.

Trait Implementations

impl Clone for CachedFBig

fn clone(&self) -> CachedFBig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CachedFBig

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>
