Sorry for the last reply - I had the wrong subject line. I have nailed down
that it seems that the BOOL is being returned as something other than char 1 ||
char 0 from the private framework where the category exists. The following
works though, I know it's bad to use NSInteger values instead of BOOL but at
this point I am at a dead end....
//=========== WORKS
-(BOOL)isLessThanZero
{
NSInteger theInteger = 0;
if ([[NSDecimalNumber zero] compare:self] == NSOrderedDescending)
{
theInteger = 1;
}
return theInteger;
}
