SId
) from the model in preference to pre-defined MathML symbols More precisely, the Model entities whose identifiers will shadow identical symbols in the mathematical formula are: Species, Compartment, Parameter, Reaction, and SpeciesReference. For instance, if the parser is given a Model containing a Species with the identifier "pi
", and the formula to be parsed is "3*pi
", the MathML produced by the parser will contain the construct <ci> pi </ci>
instead of the construct <pi/>
. Another example, if the passed-in Model contains a FunctionDefinition with the identifier "sin
", that function will be used instead of the predefined MathML function <sin/>
. log
with a single argument ("log(x)
") can be parsed as log10(x)
, ln(x)
, or treated as an error, as desired. - -3
") from the input and incorporate single unary minuses into the number node, or (2) preserve all minuses in the AST node structure, turning them into ASTNode objects of type AST_MINUS number id
" can be interpreted as a numerical value number
followed by units of measurement indicated by id
, or it can be treated as a syntax error. (In Level 3, MathML <cn>
elements can have an attribute named units
placed in the SBML namespace, which can be used to indicate the units to be associated with the number. The text-string infix formula parser allows units to be placed after raw numbers; they are interpreted as unit identifiers for units defined by the SBML specification or in the containing Model object.) avogadro
can be parsed either as a MathML csymbol or as a identifier. More specifically, "avogadro
" can be treated as an ASTNode of type AST_NAME_AVOGADRO or of type AST_NAME
