In the article
Http://dev.9cbs.net/Article/53/53449.SHTM, the author said that Delphi's four rounds have bugs! ?
On the contrary, I think Borland is very comprehensive, this is not bug!
Delphi helps writing clearly!
SimpleroundTo: Self-consting volume (asymmetric) practice)
RoundTo: Si Zhixi, five entries (banker practices)
RoundTo (1.235, -2) = 1.24
RoundTo (1.245, -2) = 1.24
Roundto is a banker's approach.
SimpleroundTo is our usual, all-time!
