/**
 * Inverse error function.
 *
 * Computes the inverse of the error function.
 *
 * The inverse error function satisfies `y = erf(x)`, for `-1 ≤ y ≤ 1` and `-∞ ≤ x ≤ ∞`.
 *
 * @param y A real value in the range [-1, 1]
 * @returns The value of the inverse error function
 * @throws If the input is out of range
 *
 * @example Compute the inverse error function for a positive value
 * ```ts
 * import { assertEquals } from "jsr:@std/assert";
 *
 * assertEquals(erfinv(0.1), 0.08885596505119556);
 *
 * ```
 *
 * @example Compute the inverse error function for a negative value
 * ```ts
 * import { assertEquals } from "jsr:@std/assert";
 *
 * assertEquals(erfinv(-0.5), -0.47693623612190483);
 *
 * ```
 *
 * @example Compute the inverse error function for 0 (should return 0)
 * ```ts
 * import { assertEquals } from "jsr:@std/assert";
 *
 * assertEquals(erfinv(0), 0);
 *
 * ```
 *
 * @example Compute the inverse error function for 1 (should return positive infinity)
 * ```ts
 * import { assertEquals } from "jsr:@std/assert";
 *
 * assertEquals(erfinv(1), Infinity);
 *
 * ```
 *
 * @example Compute the inverse error function for -1 (should return negative infinity)
 * ```ts
 * import { assertEquals } from "jsr:@std/assert";
 *
 * assertEquals(erfinv(-1), -Infinity);
 *
 * ```
