8//! Fixed point arithmetic helpers mirroring `<lib/fixed_point.h>`.
9//!
10//! The central type is [`Fp3264`], a 32.64 unsigned fixed point number (32
11//! integer bits and 64 fractional bits) used by platform timer code to convert
12//! between clock domains (e.g. TSC ticks to nanoseconds) without floating
13//! point.
