Very easy issue with division

I'm sure this is something very simple, but I've been messing around and can't figure it out...

I read in a value and store it as a 1x1 int32. Say the variable is resolution and its value is 100,000.

resolution/1e6
ans=0

No. But it I do:

x=100000;
x/1e6
and=0.1

Which is correct. Something is odd and I can't figure it out.

Answer 1

do a

whos(resolution)
whos(x)

You will find that x is a double and resolution is an int32. Since resolution/1e6 is cast as an int32 is comes out 0
