 +====== Inverse Tangent (Expression Function) ======
  
 +===== Purpose =====
 +The **Inverse Tangent** function (ATAN) is used to calculate the inverse, arc, [[Expression Function - Tangent|tangent]] in radians, degrees, or gradians. ​
 +
 +{{::​atan_initial.png?​direct&​600|}}
 +
 +===== Parameters =====
 +The **Inverse Tangent** function has two parameters, the first of which is required:
 +
 +==== Value ====
 +
 +Allowed Inputs: [[Field|field]] value or number
 +
 +The first required parameter is the value that the inverse tangent will be obtained from either use the use the [[Query Builder]] to choose a field that contains the value or use type a value to enter a number.
 +
 +==== Angle Unit ====
 +
 +Allowed Inputs: omitted, '​d',​ '​g' ​
 +
 +The second parameter of the **Inverse Tangent** function is the unit of the angle returned. If the angle unit is omitted or not recognized then radians will be be used.  For an angle provided in degrees use '​d'​. ​ For an angle provided in gradians use '​g'​. ​ If the angle unit needs to be dynamically stored in a field then the advanced expression builder will need to be used.
 +
 +
 +===== Output =====
 +
 +The output of the **Inverse Tangent** function is a number representing the arc tangent of the angle in radians.
 +
 +===== Example =====
 +
 +For example ATAN(0.57735026919) is "​0.523598775599",​ ATAN(0.57735026919,'​d'​) is "​30",​ and ATAN(0.57735026919,'​g'​) is "​33.3333333333"​.
