[yt-users] int/long error

[Kaitlin Kratter]

Hi Matt,

Just to be clear, the left_edge arguments need to be int32s? I'm confused because the example had floats for the left and right edge values...

By the way, the undergrad just left so it will take a little time to verify in any case.

Best,
Kaitlin
