Binary Operations

Prefer `@.` for multi-op elementwise expressions so every operator is dotted. Missing a dot silently changes the meaning and can prevent broadcast fusion. See [Kernel Fusion](perf/kernel_fusion.md).

The following binary operations are supported and can be applied elementwise to pairs of NDArray values:

• +, -, *, /, ^, <, <=, >, >=, ==, !=, atan, hypot, max, min, lcm, gcd
