     58    * Calculate the inverse tangent function with two arguments, y/x.
     59    * By providing two arguments, the right quadrant of the computed angle can be
     60    * determined.
     61    *
     62    * For matrices, the function is evaluated element wise.
     63    *
     64    * Syntax:
     65    *
     66    *    math.atan2(y, x)
     67    *
     68    * Examples:
     69    *
     70    *    math.atan2(2, 2) / math.pi       // returns number 0.25
     71    *
     72    *    const angle = math.unit(60, 'deg') // returns Unit 60 deg
     73    *    const x = math.cos(angle)
     74    *    const y = math.sin(angle)
     75    *
     76    *    math.atan(2)             // returns Complex 1.5707963267948966 -1.3169578969248166 i
