* Calculate the inverse tangent of a value.

|
|
* For matrices, the function is evaluated element wise.

|
|
* Syntax:
|
|
*
|
|
* math.atan(x)

|
*
|
|
* Examples:
|
|
*
|
|
* math.atan(0.5) // returns number 0.4636476090008061
|
|
* math.atan(math.tan(1.5)) // returns number 1.5
|
|
*
|
|
* math.atan(2) // returns Complex 1.5707963267948966 -1.3169578969248166 i
