Required Methods§

source

fn class(&self) -> Self::Class

Get an impl of NumberClass describing this number.

source

fn into_type( self, dtype: <Self as NumberInstance>::Class ) -> <<Self as NumberInstance>::Class as NumberClass>::Instance

Cast this number into the specified NumberClass.

source

fn abs(self) -> Self::Abs

Calculate the absolute value of this number.

source

fn exp(self) -> Self::Exp

Raise e to the power of this number.

source

fn ln(self) -> Self::Log

Compute the natural logarithm of this number.

source

fn log<N: NumberInstance>(self, base: N) -> Self::Log
where Float: From<N>,

Compute the logarithm of this number with respect to the given base.

source

fn pow(self, exp: Number) -> Self

Raise this number to the given exponent.

Panics: if the given exponent is a complex number.

source

fn round(self) -> Self::Round

Return this number rounded to the nearest integer.

Provided Methods§

source

fn and(self, other: Self) -> Self
where Boolean: CastFrom<Self>,

Return true if self and other are nonzero.

source

fn not(self) -> Self
where Boolean: CastFrom<Self>,

Return true if this number is zero.

source

fn or(self, other: Self) -> Self
where Boolean: CastFrom<Self>,

Return true if self or other is nonzero.

source

fn xor(self, other: Self) -> Self
where Boolean: CastFrom<Self>,

Return true if exactly one of self and other is zero.
