But why does it round 895.000000 to 894?

As others have explained, it's not actually doing that.

I just wanted to point out that what you get depends upon the precision of perl's NV (floating point type).
If perl's NV is the 64-bit precision long double, then you'll get what you expected: 
D:\>perl -le "$x = 8.95 * 100; print int($x);"
895

Otherwise you get what you did not expect: 
D:\>perl -le "$x = 8.95 * 100; print int($x);"
894

(For some precisions, the closest binary approximation of 8.95 is less than 8.95, for other precisions it's greater than 8.95.)
To determine perl's NV type, just run: 
D:\>perl -V:nvtype
nvtype='long double';
