This works for non-negative numbers:

[* 1000]
[+ 0.5]
[/ 1000]

For negative numbers, it seems [int] truncates towards 0, which is a bit

Also try

[expr floor($f1,0)]

[expr ceil($f1,0)]

Which reminds me to ask, does anyone know why expr's floor and ceil
require two arguments, and would it make sense to allow floor and ceil
to work with a single argument only?

expr: syntax error: function 'floor' needs 2 arguments

error: expr: syntax error
... you might be able to track this down from the Find menu.
 expr floor($f1)
... couldn't create
