Pow

Atan2

Two-argument arctangent atan2(a, b) with operands (y, x).

CEntropy

a·ln(a/b) — GAMS centropy. No .nl opcode; in-memory Expr only.

Fused for the same reason as UnaryOp::XLogX, plus one of its own: ∂²/∂b² is a/b², and b² overflows for |b| > 1.3e154 while a/b² itself stays comfortably in range. The fused rule evaluates it as q/b with q = a/b and never squares anything.
