[info-cgicc] RE: [help-cgicc] Limits in getDoubleValue and getIntegerValue

[Stephen F. Booth]

I added these methods to the CVS version of cgicc - look for a new
version in a week or so.  Basically I added the following to FormEntry:
getIntegerValue(int, int, bool&) and getDoubleValue(double, double,
bool&).  The bool& is set to true or false depending on whether or not
the value was clamped to the limits.  Also, the bug fix for
getDoubleValue (the bug you reported) is in there as well.
