Asuming that you want to print that variable,
add a text field to your Detail section and
set its expression property to something like:
($F{field1}.intValue() == $F{field2}.intValue()) ?
new Integer(1) :
new Integer(($F{field2}.intValue() - $F{field1}.intValue()) * 24)
If field1 and field2 are Doubles use Double instead of Integer and
doubleValue() instead of intValue()
