An error/mistake in Easom function

[shar3579]

When i tried to import landscapes library and use easom function in it, The error below occurs because the Easom function has a calculation issue.

Error:

    747    
    748     x, y = xy[0], xy[1]
--> 749     return -cos(x)*cos(y)*exp(-((x-pi)**2 - (y-pi)**2))

OverflowError: math range error

Correct Formula:
-cos(x)cos(y)exp(-((x-pi)**2 + (y-pi)**2))
