Library functions

Hi All:

  The XSL specs defines a number library functions in section 5.10.  I am
not
exactly sure how those functions are to be used.  Is the following piece
of psedo code has the correct idea:

    <fo:block
            border-before-width = "floor(4.2 div 2.0)*1.0in"
   </fo:block>

Also are the units required inside the function arguments  (i.e. 4.2in, and
2.0in)?
The specs seems to indicate yes but the implementations I am using
complain about that big time.  Any examples of the library functions will be
greatly appreciated.

Greetings,
Carmelo Montanez
