+   * Calculate the inverse tangent of a value.

+   * To avoid confusion with matrix arctangent, this function does not apply

+   *
+   *    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
