Hi all,
I am using my own class for converting an integer number in a binary mode:

...
Value ConvertBinShort::Scan(const Value& text) const 
{
	Value v = UPP::ScanInt((const char*)String(text), NULL, 2);
	if(IsError(v)) return v;
	if(IsNull(v)) return notnull ? NotNullError() : v;
	int m = v;
>>>>>>	if(m > 0x7FFF) m = 0xFFFF - m;		
	if(m >= minval && m <= maxval) return v;	
	return ErrorValue(UPP::Format(t_("Number must be between %X and %X."), minval, maxval));
}
...

For every type of number: char, short, int and int64 I have a different class. The same problem for Octal ed Hexadecimal converters.

In fact, I don't found any solution for get the type of the number from Value.

v.GetType() == INT_V
v.GetType() == INT64_V

or

v.Is<int>
v.Is<int64>

Not that I would recommend testing in most cases...
