Retrieves a numeric value from the OPER
[C++]
double ToDouble(
BOOL bStrict = FALSE
) const;
If bStrict is FALSE (the default) then, if the COper does not contain a double, the function will safely return an appropriate converted double (0 for blanks).
If bStrict is TRUE then the function will assert unless the COper contains a double.
This function returns the double value contained in a COper.
