8.9.6.21.1 Semantic definition

The function compares two numerical values and ensures that they are the same (with an epsilon precision factor). In the function the following questionable ad-hoc value is used: 0.000001 for the default precision (1E-6)

8.9.6.21.2 Formal representation

FUNCTION IfcSameValue
(Value1, Value2 : REAL; Epsilon : REAL)
: LOGICAL;
LOCAL
ValidEps : REAL;
DefaultEps : REAL := 0.000001;
END_LOCAL;
ValidEps := NVL(Epsilon, DefaultEps);
RETURN ((Value1 + ValidEps > Value2) AND (Value1 < Value2 + ValidEps));
END_FUNCTION;

Last change: Improve definition split (#876) * bring back headers headers were previously removed by mistake, now bringing them back * add new lines and rename the tag add the word 'short' in it * unify newlines make exactly one newline before and two after the tag * resolving typos Because bringing back headers required to go back in time to previous version, I'm now re-resolving the issues: #861, #860, #856 by ArturTomczak on 2024-07-16T16:07:28+02:00
