truncating negative numbers
in [Matlab]

From: Dolchut on 8 Jul 2010 08:36 Hi, say I have the following three negative numbers: -151.5 -48.78 -32.23 and I just want to truncate it so that the negative integer part remains (removing the decimal). I do not want to round or floor it. And as the number size varies (151, 48, 32), I cannot use precision either... the result should look like: -151 -48 -32 It may sound trivial but could use some hint... cheers

Had I no idea how to solve your problem, I might read the help for floor, or round, two functions that are close to what you want to do. Upon doing, I would see the reference to other, similar functions. Ceil, for example, or fix. I might then look at what those functions do. Since you have not fully specified your problem, I can't know which of these functions might help you. For example, what behavior do you wish to see on positive numbers? Regardless, use of the help that comes with matlab will solve your problem. John

I do not want to round or floor it. Then you want to CEIL it. > And as the number size varies (151, 48, 32), I cannot use precision either... I don't know what "using precision" is. Good luck, Jan
