Crystal Reports formatting number in a concatenated group header

Message

     How can I fomat a number output within a Group header so that the numbers appear formatted without decimal places? 

Group header formula:

if {@forDaysLate} < 0 then "number of orders "&truncate({@forDaysLate})&" days late =" else if 
{@forDaysLate} > 0 then "number of orders "&truncate({@forDaysLate})&" days early =" else "number of orders on time ="

forDaysLate formula

Datediff("d",datevalue({RELFBL.BELEGDATLIEF}) ,datevalue({RELFB.SEGM2_TERM}))

I was hoping that the 'truncate' function would remove the '.00' from the number of days late.

example output:

number of orders -3.00 days late =

number of orders on time =

number of orders 5.00 days early =

If I put the 'forDaysLate' formula in the report, I can format the number using right click -> format field.

How do I do it within a formula??

It would be helpful to remove the negative symbol '-' from the 'days late' number as well.

Any ideas guys?
