Thanks James. I'm being deliberately lazy here. 'floor' 'ceil' and 'int' have very particular specification in C in terms of whether they return an integer or a float. (Even in Perl, 3.0 is different from 3). Also they may round towards zero or negative infinity. For example, func(-3.5) may be -3, -4, -3.0 or -4.0. Anyone care to elaborate? Rob BTW, I can't stomach 'foo' or 'bar'. It makes me nauseous just to type them. -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
