Function sqrt 

pub fn sqrt<T>(item: T, error: T) -> T
where
    T: Fixed,

Numerical square root of a fixed point scalar. Slow but acurate method.

Argument

• error - The gratest allowed error in the result.

Example

use fixed::{types::extra::U20, FixedI32};
use integer_array::utility as util;
let x = util::sqrt( FixedI32::<U20>::from_num(110), FixedI32::<U20>::from_num(0.025) );
assert_eq!{  x.to_num::<f32>(), 10.488159f32 };
