Description

The inverse of tan(), returns the arc tangent of a value. This function expects the values in the range of -Infinity to Infinity and values are returned in the range -HALF_PI to HALF_PI.

This function makes a call to the numpy atan() function.

Syntax

atan(value: float) -> float

Parameters

  • value: float - value whose arc tangent is to be returned
