2014 vs . 2013 sales of $ 450.4 were relatively flat as higher liquefied natural gas ( lng ) project activity was offset by lower air separation ( asu ) project activity . operating income of $ 88.2 increased from the higher lng project activity . the sales backlog for the equipment business at 30 september 2014 was $ 520 , compared to $ 402 at 30 september 2013 . the increase was primarily due to new lng orders as global project development activity remains high . it is expected that approximately $ 320 of the backlog will be completed during 2015 . 2013 vs . 2012 sales of $ 451.1 increased primarily from higher lng project activity . operating income of $ 65.5 increased from the higher lng project activity . the sales backlog for the equipment business at 30 september 2013 was $ 402 , compared to $ 450 at 30 september other operating income ( loss ) primarily includes other expense and income that cannot be directly associated with the business segments , including foreign exchange gains and losses . also included are lifo inventory valuation adjustments , as the business segments use fifo , and the lifo pool valuation adjustments are not allocated to the business segments . other also included stranded costs resulting from discontinued operations , as these costs were not reallocated to the businesses in 2012 . 2014 vs . 2013 other operating loss was $ 13.5 , compared to $ 4.7 in the prior year . the decrease was primarily due to unfavorable foreign exchange losses of $ 5 and lifo adjustments of $ 4 . 2013 vs . 2012 other operating loss was $ 4.7 , compared to $ 6.6 in the prior year . the other operating loss in 2013 includes an unfavorable lifo adjustment versus the prior year of $ 11 . the other operating loss in 2012 included stranded costs from discontinued operations of $ 10. .
Question: what was the operating margin for 2014?


Answer: The answer is:0.19583
