Division by zero warnings

[cunhasdepedra]

@djoffrey Hey, I'm also getting this:

:823: RuntimeWarning: invalid value encountered in double_scalars
XAD = abs(A-D) / abs(X-A)
:946: RuntimeWarning: invalid value encountered in double_scalars
XAD = abs(A-D) / abs(X-A)
:1055: RuntimeWarning: invalid value encountered in double_scalars
XAD = abs(A-D) / abs(X-A)
:1177: RuntimeWarning: invalid value encountered in double_scalars
XAD = abs(A-D) / abs(X-A)
:123: RuntimeWarning: invalid value encountered in double_scalars
XAD = abs(A-D) / abs(X-A)
:1180: RuntimeWarning: invalid value encountered in double_scalars
XCD = abs(D-C) / abs(X-C)

From what I was able to check, it's not compromising my patterns validation. But I would like to hear from you too.

Let me be more precise: those warnings compromise the calculations that lead to the patterns formation? So I might be getting wrong patterns?

I can't not 100% sure, but if the X-C near 0, the float part may be importance, but that wont fit in the patterns.
if you need the ensure the accuracy, do some type convert to avoid this msg.
