[Tutor] 2.5 to 2.4 problem with Int

[John]

The error occurs here:
area[ix,iy]=gridarea

The values of nx, ix, iy leading up to the error are:
360 0 0
360 1 0
360 2 0
360 3 0
360 4 0
360 ... ...
360 357 9
360 358 9
360 359 9
360 0 10
OverflowError: long int too large to convert to int

I guess then the problem occurs when iy goes from 9 to 10, but why?? It
wasn't a problem before and it's not a problem for ix???

Thanks!
