All-encapsulating trait for finite precision floats.
Required Methods
fn zero(precision: usize) -> Self
Constructs a float representing zero.
fn neg_zero(precision: usize) -> Self
Constructs a float representing negative zero.
fn one(precision: usize) -> Self
Constructs a float representing one.
fn infinity(precision: usize) -> Self
Constructs a float representing positive infinity.
fn neg_infinity(precision: usize) -> Self
Constructs a float representing negative infinity.
fn nan(precision: usize) -> Self
Constructs a float representing NaN.
fn sign(&self) -> Sign
Returns the sign of self.
fn precision(&self) -> usize
Returns the precision of self.
fn is_finite(&self) -> bool
Whether self is a regular number (non-infinity and non-NaN).
fn is_infinite(&self) -> bool
Whether self is either positive infinity or negative infinity.
fn is_zero(&self) -> bool
Whether self is zero (or negative zero).
fn is_infinity(&self) -> bool
