MATLAB: Floor function for int8

Question

I want to round down (floor) variable defined as int8 without converting to double !

for example: a=int8(8.6);

I want the result will equal to 8 instead of 9. Is there way to do or it impossible (without converting to double) ? The reason I need it, because I work with large matrix (25000×25000) of int8.

Thanks Alex

Answer 1

Using your later example,

 idivide(a,4,'floor')

does what you want there. I prefer to make both arguments integers of the same type, so I would probably have written

 idivide(a,int8(4),'floor').

Note that the default option for idivide is 'fix', which might be what you want. Obviously, 'floor' and 'fix' are the same for non-negative quotients. -- Mike
