A floating-point CType

Required Methods

fn is_inf(self) -> bool

Return true if this Float is infinite (positive or negative infinity).

fn is_nan(self) -> bool

Return true if this Float is not a number (e.g. a float representation of 1.0 / 0.0).

fn exp(self) -> Self

Exponentiate this number (equivalent to consts::E.pow(self)).

fn ln(self) -> Self

Return the natural logarithm of this Float.

fn log(self, base: Self) -> Self

Calculate the logarithm of this Float w/r/t the given base.

fn sin(self) -> Self

Return the sine of this Float (in radians).

fn asin(self) -> Self

Return the arcsine of this Float (in radians).

fn sinh(self) -> Self

Return the hyperbolic sine of this Float (in radians).

fn cos(self) -> Self

Return the cosine of this Float (in radians).

fn acos(self) -> Self

Return the arcsine of this Float (in radians).

fn cosh(self) -> Self

Return the hyperbolic cosine of this Float (in radians).

fn tan(self) -> Self

Return the tangent of this Float (in radians).

fn atan(self) -> Self

Return the arctangent of this Float (in radians).

fn tanh(self) -> Self

Return the hyperbolic tangent of this Float (in radians).

fn to_f64(self) -> f64

Cast this Float to an f64.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
