Hi,
I need to find the square root of a number in a program I am writing. I have
imported the 'math' module so I thought I could just call sqrt(x) but I get an
error message. Extact from my code and error message below.
import sys, pygame, math
...
if ypos >= 384 and velocity > 0:
impactvel = sqrt(velocity ** 2 + (2 * gravity * (ypos - 384 * 160)))
...
Traceback (most recent call last):
File "<stdin>", line 32, in <module>
ValueError: math domain error
This one has me stumped as the usage of the module looks straight forward from
the documentation. Thanks for looking.
Matt
