It seems that the numberFormat is taking precedence here.
If you try this in the message box:
   put trunc(1.00)
or
   put round(1.00)
you will get 1 as expected, but in your sample, the y is being
truncated, then the 2 decimal places are being re-applied for the
answer. You can check that this is what is happening by setting y to
something like 1.23, which makes your "answer" display 1.00

As a general rule, I much prefer using the format function to the
numberFormat. I feel that I have more control that way, since it is
only applied to numbers that I want to apply it to, instead of all
numbers which is what causes problems like the one with the field
reference.
