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!
