Question: considering the year 2016 , what is the percentage of stock options that were excluded from the computation due to its anti-dilutive effect?
Evidence:
table_3: in millions the weighted-average number of diluted shares of 2016 is 96.9 ; the weighted-average number of diluted shares of 2015 is 96.9 ; the weighted-average number of diluted shares of 2014 is 97.2 ;
text_1: at december 31 , 2016 , 0.6 million stock options were excluded from the computation of weighted average diluted shares outstanding because the effect of including these shares would have been anti-dilutive .
Program: divide(0.6, 96.9)
