Trying to see if a variable is an integer or not

x=2.5;
isaninteger = @(x)isfinite(x) 
x=floor(x)
 answer=isaninteger(x)

I want the answer here to show that x is not an integer but all it shows is answer = 1. No idea how to fix this

The correct output here would be answer = 0

Answer 1

Try this

%%
x=2.5;
answer = ( x == floor(x) )

answer = logical
   0

Another possibility —

x = 2.5;
answer = rem(x,1)==0

answer = logical
   0

answer = mod(x,1)==0

answer = logical
   0
