Math

Named mathematical constants, matching Rust’s f64::consts surface.

Purely additive: the transcendental functions (sin, cos, exp, ln, sqrt, …) stay owned builtins routing through the vendored libm, and pi/e/tau stay Base-global. This module only names the derived constants, as exact Float literals pinned bit-for-bit, so importing it never shadows a Base name. Opt-in: not in Base.
