Hello,

I am noticing small differences in floating point values returned by the Maya API between the 32 bit and 64 bit versions.

Specifically, when I call MFnMesh::getPoints(MFloatPointArray& ...), the vertices have slightly different - but nearly identical - values.

Is this to be expected?  Perhaps the internal precision of certain operations in Maya differs in the two versions?

This is not the end of the world, but it does mean that data from the same scene is not binary identical when exported using the different versions of Maya, which is certainly a pit of a pain.

Any insight would be much appreciated.

Thanks,

-Nicolas
