When encoding binary values, only base 2 is supported

Variants

`Binary`

Fields

mantissa: f64

base: u32

exponent: i32

enc_base: u8

Non-special values

`Infinity`

Infinity (∞).

`NegInfinity`

Implementations

impl Real

pub fn new(f: f64) -> Real

Create a new REAL from the f64 value.

pub const fn with_enc_base(self, enc_base: u8) -> Real

pub const fn binary(mantissa: f64, base: u32, exponent: i32) -> Real

Create a new binary REAL

pub fn is_infinite(&self) -> bool

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

pub fn is_finite(&self) -> bool

Returns true if this number is not infinite.

pub fn f64(&self) -> f64

Returns the ‘f64’ value of this REAL.

Returned value is a float, and may be infinite.

pub fn f32(&self) -> f32

Returns the ‘f32’ value of this REAL.

This functions casts the result of Real::f64 to a f32, and loses precision.
