Float
Implementations§
source§impl Float
impl Float
sourcepub fn new(num: f64) -> Self
pub fn new(num: f64) -> Self
Creates a new Float
.
Examples
use rutie::{Float, VM};
let float = Float::new(1.23);
assert_eq!(float.to_f64(), 1.23);
Ruby:
1.23 == 1.23
sourcepub fn to_f64(&self) -> f64
pub fn to_f64(&self) -> f64
Retrieves an f64
value from Float
.
Examples
use rutie::{Float, VM};
let float = Float::new(1.23);
assert_eq!(float.to_f64(), 1.23);
Ruby:
1.23 == 1.23
sourcepub fn implicit_to_f(object: impl Object) -> Result<Float, AnyException>
pub fn implicit_to_f(object: impl Object) -> Result<Float, AnyException>
Cast any object to a Float
implicitly, otherwise
returns an AnyException
Examples
use rutie::{Integer, Float, Object, VM};
let integer = Integer::new(3);
assert_eq!(Float::implicit_to_f(integer), Ok(Float::new(3.0)));
Ruby:
Float(3) == 3.0
