Fungrim entry: 6fe5c1

Symbol: RealLimit limxaf ⁣(x)\lim_{x \to a} f\!\left(x\right) Limiting value, real variable
This operator can be called with three or four arguments.
RealLimit(f(x), x, a), rendered as limxaf ⁣(x)\lim_{x \to a} f\!\left(x\right), is equivalent to Limit(f(x), x, a, Element(x, RR)) but renders to LaTeX without displaying the predicate xRx \in \mathbb{R} which readers will typically understand from context.
RealLimit(f(x), x, a, P(x)), rendered as limxa,P(x)f ⁣(x)\lim_{x \to a, P\left(x\right)} f\!\left(x\right), is equivalent to Limit(f(x), x, a, And(Element(x, RR), P(x))).
