o ( x ) represents the least odd integer greater than x , whereas o ( x ) represents the greatest odd integer less than x . likewise , e ( x ) represents the least even integer greater than x , whereas e ( x ) represents the greatest even integer less than x . according to these definitions , the value of o ( 8.3 ) + e ( – 8.7 ) + o ( – 7.3 ) + e ( 6.6 ) is :
"o ( 8.3 ) + e ( – 8.7 ) + o ( – 7.3 ) + e ( 6.6 ) = 9 + ( - 8 ) + ( - 9 ) + 6 = - 2 the answer is a ."
add(add(add(multiply(8.3, const_1), multiply(negate(8.7), const_1)), negate(7.3)), multiply(6.6, const_1))
