Usage

cargo add lufloat

use lufloat::{Arena, UnifiedBuffer};

let arena = Arena::new(2048);
let mut buffer = UnifiedBuffer::new(&arena, 2048);
let input_data = buffer.slice_mut();

input_data[0] = 0b1_01111_0000000000; // -1.0
input_data[1] = 0b0_00000_0000000000; // 0.0
input_data[2] = 0b0_01111_0000000000; // 1.0

buffer.positive_mask_inplace();
let output_data = buffer.slice();

println!("The first 3 elements are: {:?}", &output_data[..3]); // 0.0, 1.0, 1.0
