Rounding Modes For Floating Operations

At the moment there is no way to specify specific rounding floating pointing operations. since we are able to specify extra symbols along with standard operator for some operations like Wrapping Addition (+%), Saturating Addition (+|), and etc. In the same way, can we add some additional symbols to the language to specify rounding modes for floating point operations. like +{some symbol} for the followings: Round to Nearest, ties to Even.
