Void AssignDouble ( double that )
From FM Plugin Wikipedia
Assign Double
This function allows you to set a 'FixPt' with a 'Double' value.
In some situations, you may find it easier to work with C++'s Double as it provides more calculation options, but then you will want to return the calculated result back to the user.
In the following example, we will assign a Double to a FixPt, and then set it's precision to the default of 16
double value; fmx::FixPtAutoPtr result; value = 19.2 ; result->AssignDouble( value ); result->SetPrecision( fmx::FixPt::kDefltFixedPrecision );
In the next example, we will also set the FixPt as out return 'results'
FMX_PROC(fmx::errcode) MyNumber(short /* funcId */, const fmx::ExprEnv& /* environment */, const fmx::DataVect& /*dataVect */, fmx::Data& results ) { double valueDouble; fmx::FixPtAutoPtr valueFixPt; valueDouble = 19.2 ; // assign our 'double' number valueFixPt->AssignDouble( valueDouble ); // store our 'double' in a 'FixPt' valueFixPt->SetPrecision( fmx::FixPt::kDefltFixedPrecision ); // set the precision to 16 (default) results.SetAsNumber( *valueFixPt ); // return as our result to FileMaker return 0; // no error }
