IfcReal: public IfcUtil::IfcBaseType¶
IfcReal is a defined type of simple data type REAL. It is required since a select type (IfcSimpleValue), cannot directly include simple types in its select list.
In principle, the domain of IfcReal (being a Real) is all rational, irrational and scientific real numbers. Here the precision is unconstrained, but in practice it is implementation specific.
HISTORY: New type in IFC Release 1.5.1.
