Try a function, like int32(), fix(), ceil(), floor(), uint8(), int32(round()), etc.
a = (2+24)/(4*3) % Floating point.
aInteger = int32(a)
whos aInteger; % int32
aInteger = round(a)
whos aInteger; % Double
aInteger = floor(a)
whos aInteger; % Double
aInteger = ceil(a)
whos aInteger; % Double
aInteger = fix(a)
whos aInteger; % double
aInteger = uint16(a)
whos aInteger; % uint16
Note that with round(), ceil(), floor(), and fix() you will end up with a double but with no fractional part. If you want an actual integer, you have to cast to an integer data type with int32(), int16(), etc.

Because the result is not an integer. To convert from decimal to integer, use one of these functions:
round, floor, ceil
