Float-point value.

Required Methods

fn abs(self) -> T

Get absolute value.

fn floor(self) -> T

Returns the largest integer less than or equal to a number.

fn ceil(self) -> T

Returns the smallest integer greater than or equal to a number.

fn trunc(self) -> T

Returns the integer part of a number.

fn round(self) -> T

Returns the nearest integer to a number. Round half-way cases away from 0.0.

fn nearest(self) -> T

Returns the nearest integer to a number. Ties are round to even number.

fn sqrt(self) -> T

Takes the square root of a number.

fn is_sign_positive(self) -> bool

Returns true if the sign of the number is positive.

fn is_sign_negative(self) -> bool

Returns true if the sign of the number is negative.

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

Returns the minimum of the two numbers.

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

Returns the maximum of the two numbers.

fn copysign(self, other: T) -> T

Sets sign of this value to the sign of other value.

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.
