Void SetPrecision ( int precision )
From FM Plugin Wikipedia
SetPrecision
This function allows you to specify the Percision to use for FixPt numbers.
The default is 16 (as set in fmx::FixPt::kDefltFixedPrecision )
This is necessary if you AssignDouble, to ensure a number like 0.2 doesn't get shown in FileMaker as 0.1999999999999
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 );
