Required Methods

fn is_sign_positive(&self) -> bool

Is the sign of this real number positive?

fn is_sign_negative(&self) -> bool

Is the sign of this real number negative?

fn copysign(self, sign: Self) -> Self

Copies the sign of sign to self.

• Returns self.simd_abs() if sign is positive or positive-zero.
• Returns -self.simd_abs() if sign is negative or negative-zero.

fn max(self, other: Self) -> Self

fn min(self, other: Self) -> Self

fn clamp(self, min: Self, max: Self) -> Self

fn atan2(self, other: Self) -> Self

fn min_value() -> Option<Self>

The smallest finite positive value representable using this type.

fn max_value() -> Option<Self>

The largest finite positive value representable using this type.

fn pi() -> Self

fn two_pi() -> Self

fn frac_pi_2() -> Self

fn frac_pi_3() -> Self

fn frac_pi_4() -> Self

fn frac_pi_6() -> Self

fn frac_pi_8() -> Self

fn frac_1_pi() -> Self

fn frac_2_pi() -> Self

fn frac_2_sqrt_pi() -> Self

fn e() -> Self

fn log2_e() -> Self

fn log10_e() -> Self

fn ln_2() -> Self

fn ln_10() -> Self

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.
