   * Calculate the inverse tangent of a value.
   *
   * To avoid confusion with matrix arctangent, this function does not apply
   * to matrices.
   *
   * Syntax:
   *
   *    math.atan(x)
   *
   * Examples:
   *
   *    math.atan(0.5)           // returns number 0.4636476090008061
   *    math.atan(2)             // returns number 1.1071487177940904
   *    math.atan(math.tan(1.5)) // returns number 1.5
   *
   * See also:
   *
   *    tan, asin, acos
   *
   * @param {number | BigNumber | Complex} x   Function input
   * @return {number | BigNumber | Complex} The arc tangent of x
