Derivative and special purpose operators with function syntax, see.

Mathematical functions and conversion functions, see Section Numeric Functions and Conversion Functions.

Intrinsic means that they are defined at the Modelica language level, There are also built-in functions that depend only on the inputĪrgument, but also may trigger events in addition to returning a value. However, they do not behave as a mathematical function,īecause the result depends not only on the input arguments but also on IfĮither v1 or v2 or both variables are a subtype of Real, the relationīuilt-in Intrinsic Operators with Function Syntax ¶Ĭertain built-in operators of Modelica have the same syntax as aįunction call. Rel_op a relational operator are called elementary relations.

Relations of the form v1 rel_op v2, with v1 and v2 variables and.Number length in registers is different to number length in main On equality of Real variables is questionable on machines where the two crossing functions instead of one crossing function needed,Įpsilon strategy needed even at event instants). Unnecessarily complicated for the = and relational operators Rule is that relations with Real arguments are transformed to stateĮvents (see Events, Section 8.5 ) and this transformation becomes Used in a function, not be a subtype of Real. For operands of type Boolean, false v2, v1 or v2 shall, unless.Operator, op, defined in terms of the C-function strcmp as For operands of type String, str1 op str2 is for each relational.The result is Boolean and is true orįalse if the relation is fulfilled or not, respectively. Relational operators, >=, =, ``, are only defined for.The following holds for relational operators: Those shown as unary together with expr, the conditional operator, theĪrray construction operator logical_factor = relation relation = arithmetic_expression rel_op = "" | ( ">=" ) | ( "=" ) | ( "" ) All operators are binary except the postfix operators and

Precedence from highest to lowest, as derived from the Modelica grammar The following table presents all the expression operators in order of Operator with lower precedence in the same expression.

An operator with higher precedence is evaluated before an Operator precedence determines the order of evaluation of operators inĪn expression.
