Sorting Values my Integer and Decimal Values

Hello, I am attempting to create a poker hand Analyser. Right now I have all cards (2-A) correlated to an integer value (2-14). Then depending on their Suite (Heart, Diamond,Spade,Club) I add a decimal value ( .1, .2, .3, .4). Is there a way to have my code differentiate between the integers and decimal values?

For ex.) A pair would be 8.1 and 8.2.

and a flash would be 2.1 , 3.1 , 4.1, 5.1, 6.1

I want to say something like:

if integer= integer then hand is a pair

if deciemal = deciemal then we have a flush

Thank you

[Chunru]

p = [8.1  8.2];
if floor(p(1)) == floor(p(2))
    disp("A pair.")
end

A pair.

f = [2.1 , 3.1 , 4.1, 5.1, 6.1];
if all(abs(diff(mod(f,1))) < 1e-5)
    disp("A Flush")
end

A Flush
