Implementations

impl Float

pub const NEG_INFINITY: Self

pub const INFINITY: Self

pub const MIN: Self

pub const MAX: Self

pub const NAN: Self

pub fn new(f: f32) -> Self

pub fn is_nan(&self) -> bool

Returns true if this value is NaN.

pub fn is_finite(&self) -> bool

Returns true if this number is neither infinite nor NaN.

pub fn is_infinite(&self) -> bool

Returns true if this value is positive infinity or negative infinity, and false otherwise.

pub fn is_positive(&self) -> bool

Returns true if self has a positive sign, including +0.0, NaNs with positive sign bit and positive infinity.

Note that IEEE 754 doesn’t assign any meaning to the sign bit in case of a NaN, and as Rust doesn’t guarantee that the bit pattern of NaNs are conserved over arithmetic operations, the result of is_positive on a NaN might produce an unexpected result in some cases. See explanation of NaN as a special value for more info.

pub fn is_negative(&self) -> bool

Returns false if self has a negative sign, including -0.0, NaNs with negative sign bit and negative infinity.

Note that IEEE 754 doesn’t assign any meaning to the sign bit in case of a NaN, and as Rust doesn’t guarantee that the bit pattern of NaNs are conserved over arithmetic operations, the result of is_negative on a NaN might produce an unexpected result in some cases. See explanation of NaN as a special value for more info.

pub const fn into_f32(self) -> f32

Converts this value into a f32.
