Problem 1275. Find smallest integer type to accommodate your number

MATLAB supports 1-, 2-, 4-, and 8-byte storage for integer data. Find the smallest integer type to accomodate a scalar integer.

E.g.

a = -10;
c = findclass(a)
c =
   'int8'

or

a = 300;
c = findclass(a)
c =
  'uint16'

Always prefer unsigned integer types if the integer is greater than 0!
