IDSL-VAL-008: Exact match on a real number

Default severity	Kind	Scope	Quick fix
info	static	specification	no

The value is an exact real number on a floating-point data type. IDS 1.0 compares reals with a small relative tolerance (1e-6, see the buildingSMART tolerance test cases), which absorbs rounding but not unit conversion or modelling tolerance: 2.4 does not match 2.4004. A range states the tolerance explicitly. Tolerance handling is under discussion for IDS 1.1 (IDS issue #418).

Example

<property dataType="IFCLENGTHMEASURE">…<value><simpleValue>2.4</simpleValue></value></property>
