I saw the following in Xcalar online help
map(mult(mult(mult(div(sub(AskPrice_float, BidPrice_float), AskPrice_float),100), div(add(BidSize_float,AskSize_float),2)),100000))
Is it faster to execute nested functions? Also, is this the only way to do A+B+C in a single step, where A, B and C are columns?
