				#*								@test escape.vm								This template is used for Velocity regression testing.				If you alter this template make sure you change the				corresponding comparison file so that the regression 				test doesn't fail incorrectly.								Tests the basic integer math capabilities.								*#								Addition and subtraction : 				#set($foo = 1)				#set($foo = $foo + 1)				1 + 1 = $foo				$foo - 1 = #set($foo = $foo - 1 )$foo								Multiplication, division, and modulus :				#set($bar = 5)				#set($rem = $bar % 2)				#set($rem2 = $bar % 0)				#set($rem3 = 7%2)				$bar % 2 = $rem				$bar % 0 = $rem2				7 % 2 = $rem3				$bar / 2 = #set($rem = $bar / 2 )$rem				$bar / 0 = #set($rem4 = $bar / 0 )$rem4				$bar * 2 = #set($rem = $bar * 2 )$rem								$bar * -1 = #set($rem = $bar * -1)$rem				$bar * -2 = #set($rem = $bar *-2)$rem				$bar * -2 = #set($rem = -2*$bar)$rem								And now null nodes to make sure it doesn't throw an NPE :				#set($flargh=$woogie + $wabbie)
