WGSL

A code output form: WebGPU Shading Language source, via compute-engine's WGSL target (the WGSLForm form) — WebGPU's shader language. For scalar math it reads much like GLSL; it diverges from GLSL in typing and built-in names for anything beyond plain arithmetic and common functions.

Like any shader language it's floating-point, so exact rationals become float literals. Each row shows an expression and its WGSL source.

GPUShaderForm — the whole shader

WGSLForm is the expression alone. GPUShaderForm is the complete shader one of this site's GPU paths would run for it: with one unknown, the domain-colouring fragment shader <notatio-complex-plot> compiles (the unknown is the complex variable, and the special functions it may call — Zeta, HurwitzZeta, PolyLog — are prepended); with one or two real unknowns, the compute shader the plot grid evaluator dispatches, one invocation per grid point. Three or more unknowns, or an expression neither path can emit, has no shader form and the entry is left off the menu.
