Required Methods

fn round(x: Self) -> Self

Round to the nearest integer.

fn floor(x: Self) -> Self

Round down to the nearest integer.

fn ceil(x: Self) -> Self

Round up to the nearest integer.

fn sqrt(x: Self) -> Self

Return the number’s square root.

fn to_radians(x: Self) -> Self

Convert from degrees to radians.

fn to_degrees(x: Self) -> Self

Convert from radians to degrees.

fn atan2(y: Self, x: Self) -> Self

Computes the four quadrant arctangent of y and x in radians.

fn sin_cos(x: Self) -> (Self, Self)

Simultaneously computes the sine and cosine of the number, x. Returns (sin(x), cos(x)).

fn trunc(x: Self) -> Self

Returns the integer part of the number. This means that non-integer numbers are always truncated towards zero.

fn exp(x: Self) -> Self

Returns e^(x), (the exponential function).

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.
