Function sin 

pub fn sin(x: &DBig, precision: usize) -> OxiNumResult<DBig>

Compute sin(x) using Taylor series with argument reduction.

Examples

use oxinum_float::sin;
use std::str::FromStr;
let x = dashu_float::DBig::from_str("0.0").unwrap();
let result = sin(&x, 30).unwrap();
let s = result.to_string();
assert!(s.starts_with("0"), "sin(0) = {}", s);
