Round halfway cases away from zero, regardless of the current decimal floating point rounding mode. == Synopsis Declared in `<bdldfp_decimalimputil.h>` [source,cpp,subs="verbatim,replacements,macros,-callouts"] ---- static xref:BloombergLP/bdldfp/DecimalImpUtil/ValueType32.adoc[DecimalImpUtil::ValueType32] round(xref:BloombergLP/bdldfp/DecimalImpUtil/ValueType32.adoc[ValueType32] x); ---- == Description Special value handling: * if `x` is quiet NaN, quiet NaN is returned. * If `x` is signaling NaN, quiet NaN is returned and the value of the macro `EDOM` is stored into `errno`. * if `x` is +/‐infinity or +/‐0, it is returned unmodified. Examples: `round(0.5)` ==> 1.0; round(‐0.5) ==> ‐1.0 [.small]#Created with https://www.mrdocs.com[MrDocs]#
