## Overview
-ERF (ERror Function) is a function of the Engineering category that calculates a value for the _error function_. Also known as the _Gauss error function_, the error function represents the probability of a random variable falling within a certain range, given that it follows a specified normal distribution.

* This figure illustrates some of the key characteristics of the error function:
- * erf($0$) = $0$
- * erf($x$) = -erf($x$)
- * As $x → ∞$, erf($x$) $→ 1$.
- * As $x → -∞$, erf($x$) $→ -1$.
+ * $\text{erf}(0) = 0$
+ * $\text{erf}(x) = -\text{erf}(x)$
+ * As $x \rightarrow \infty$, $\text{erf}(x) \rightarrow 1$
+ * As $x \rightarrow -\infty$, $\text{erf}(x) \rightarrow -1$
* The error function is a [transcendental](https://en.wikipedia.org/wiki/Transcendental_function), non-algebraic mathematical function. IronCalc implements the ERF function by numerical approximation using a power series.
