Module fixed::consts [−][src]
Mathematical constants.
The constants have the maximum precision possible for a fixed-point number, and are rounded down at that precision.
Examples
use fixed::{consts, types::I4F28}; let tau = I4F28::from_num(consts::TAU); println!("τ = 2π with eight binary places is {:.8b}", tau); assert_eq!(format!("{:.8b}", tau), "110.01001000"); println!("τ = 2π with eight decimal places is {:.8}", tau); assert_eq!(format!("{:.8}", tau), "6.28318531");
