What is the purpose of new DAYS() function in Excel 2013? -

i found out excel 2013 has days() worksheet function. appears function same subtracting 1 date another. one of blogs visited said days() permits work text strings dates, found text strings work subtraction, in: ="7/15/2016"-"7/1/2016" which results in 14 when enter it, same result as =days("7/15/2016","7/1/2016") does know days() date subtraction not? thanks! days can more dynamic example create more complex formula dynamic variables =days(vlookup(c3,c5:e16,3,false),b3). in example sent more common them static. using cells can provide similar function assuming in same date , number formats. example using same formula above =vlookup(c3,c5:e16,3,false)-b3.
