Parameters:

Here is the detail of parameters:

Return Value:

The arc tangent of x, in radians.

Example:

#!/usr/bin/python
import math

print "atan(0.64) : ",  math.atan(0.64)
print "atan(0) : ",  math.atan(0)
print "atan(10) : ",  math.atan(10)
print "atan(-1) : ",  math.atan(-1)
print "atan(1) : ",  math.atan(1)

This will produce following result:

atan(0.64) :  0.569313191101
atan(0) :  0.0
atan(10) :  1.4711276743
atan(-1) :  -0.785398163397
atan(1) :  0.785398163397
