How to check decimals of a number in MATLAB?

32 views (last 30 days)
I have a question about a code. I would like to check if a value has a decimal equal to 0.5 (e.g., 5.5, 7.5 etc. ) or has a decimal equal to 0 (zero) (I mean to be integer, for example 7,5,6 etc. ).
Which command should I use? Could you please help me?

x = 5.5
x = 5.5000
integ = fix(x)
integ = 5
frac = mod(abs(x),1)
frac = 0.5000
